View Full Version : VG10 / VG20 Various Topics
Charlie Webster December 20th, 2010, 12:42 AM Was just testing tonite and there appears to be no vignetting at all with this one. Comes with it's own lens cap.
Threads are 72mm on the outside so it could take a screw on hood.
best to all

Steve Mullen December 20th, 2010, 07:18 PM I did some research on these and it seems they all introduce color shift as density increases. What have you found. The best way to check is use a color chart and AE. Dial it down slowly.
Then use the vectorscope in your NLE to monitor the position of the colors as luminance is lowered. The points shouldn't change phase or shift positions.
Try the same thing with a sheet of white paper. No position shift.
Eduardo Romero January 15th, 2011, 01:28 AM I plan on buying the VG10 by April along with a good set of lenses to cover a wide enough range. I plan on shooting a feature film with this camera so my question is, what kind of lenses (dont matter which brand) do I need to get everything from stellar low light performance, super wide shots that dont warp and that also have a good depth of field, basically which lessen do I need to replicated the look of 35mm film? Also if someone could explain to me how to "read" a lenses specs (I have no idea what any of this:f1.8/35-160mm means) just a basic primer on SLR lenses in general and which I need to get the film look and how to use each type of lens to do so, I know this is a lot to ask but I am new to this world so Im trying to educate myself as much as I can before I buy buying a bunch of random lenses, thank you in advance.
Henry Williams January 15th, 2011, 07:14 PM The f1.8 you mention is the aperture setting. This tells the camera how much light to let into the lens. Generally speaking the lower the number, the better the low light performance on that lens.
The 35mm-160mm you mention is the focal length of the lens. Basically put, this governs the size of the shot. Prime lenses have a fixed focal length eg. 50mm. The lens you describe is a zoom lens. It will go as wide as 35mm and zoom in as far as 160mm.
Some zoom lenses can have a constant aperture setting throughout their range. With others the aperture number will increase as you zoom in, letting less light into the lens. Generally prime lenses, because they are designed to work at one specific length, will give a sharper picture and allow you to use a wider aperture setting.
You CAN mount proper 35mm film camera lenses on a VG10 but it is scary expensive to even rent lenses like that, let alone buy them. I'd suggest sticking to either e-mount or SLR glass for now, and checking the excellent lens threads elsewhere on the VG10 sub forum to get a better idea of what range and type of lenses to buy. Because the VG10 multiplies the focal length of lenses by 1.6 a 35mm lens becomes approx. a 50mm lens, a 50mm lens an 80mm lens and so on. Generally speaking a basic setup would consist of a wide angle lens eg. the 16mm e-mount pancake lens, a 50mm (actually a 35mm lens) and some kind of zoom, for which the kit 18-200 lens would do fine. This is a bit of a generalisation, but the wide angle lens is for landscapes or big open shots, the 50mm is for portrait shots - mid range stuff through to close ups and the zoom lens fills in the gaps...
Cliff Totten January 27th, 2011, 12:38 PM When I play back my video files on the VG10, I noticed that the camera keeps real time function information. (Changing Fstop, gain, shutter values... etc,...)
I have this same feature in my EX1R. I can play back files in my Sony XDCAM clip browser and watch all the mechanics metadata play out in real time as it was shot.
Question; Is that data saved in the video file container? Is it somehow preserved when you dump the files to your PC in the Sony Motion Browser? If not, can the motion browser at least display that info during PC playback or is it available only on the VG10's playback screen?

Steve Mullen February 3rd, 2011, 09:01 AM So here is JVC's GC-PX1 1080p60 camcorder/camera:
HD 1080/60p (UHR) <<<< H.264/AVC at 36Mbps!
HD 1080/60p (HR)
HD 720/60p
iFrame 960x540p30
10MP BACKLIT 1/2.3" so this should have nice big photocites! Uses up to 8MP for 60p video.
Image Sensors World: Sony CX-News Tells about New Products, 2nd Generation 1.4um Pixel (http://image-sensors-world.blogspot.com/2010/02/sony-cx-news-tells-about-new-products.html)
The FalconBrid DSP will interpolate 8MP down to 2MP rather than have the CMOS sensor skip column/rows. (Skipping cuts the data going into the DSP by 3X or 6X.)
Currently sensors can't run much faster that 10fps -- therefore a 3X or 6X reduction is necessary for them as well. Which means the Sony CMOS chip must be able to run at 60fps reading out a 16:9 8MP window on the chip. In turn this means the OLPF can be optimized for 10MP for both stills and FullHD so all the crap we get from the other cameras will be gone.
Coming soon.
Sareesh Sudhakaran February 3rd, 2011, 10:18 PM JVC never ceases to amaze...Their falconbird claims to even do a 4K/2K consumer. An interchangeable lens option would have made it really exciting though...
Steve Mullen March 11th, 2011, 02:51 PM Below is a link to a page with a movie that may illuminate the relationship between the frame rate, which for NEX camera's is either 25fps or 30fps, and shutter speed.
ProVideo Coalition.com: FRESHDV by Matthew Jeppsen & Kendal Miller (http://provideocoalition.com/index.php/freshdv/story/shutter_vs_fps/)
1) For NEX owners who can't set shutter speed, pay special attention to where in changing the shutter speed slower the pix becomes over exposed until he dials the aperture smaller. This works in reverse. Had he set the aperture larger the pix would have become over exposed until the shutter speed was increased.
So NEX owner first decide shallow or deep DOF. If you want shallow, you open the aperture. Like in the movie, to get the correct exposure the camera will automatically make the shutter speed shorter. If you want deep, you close the aperture. To get the correct exposure the camera will automatically make the shutter speed longer.
2) He briefly comments on why 1/60th is correct for 30fps. The amount of motion blur, which you can see perfectly in his movie, enables the eye to see smooth motion.
3) What he didn't show was that as the shutter speed got shorter, the blade should have strobed. It didn't and that I can't explain. Perhaps that is why he didn't comment on the bad effects of high shutter speed.
4) Notice that when he uses 1/30th second for 30fps, the blur is so great that all detail in any kind of movement is lost. Goodbye to HD!
5) On the NEX camera you can't see the shutter speed before after pressing RECORD, but you can before. When it is too fast, you use an ND filter to make it slower. If it is too slow, you really have to add more light OR use a faster lens. (Or use more gain.)
In my experience, you need to own a F1.4 or F1.8 lens to keep gain low. An F2.8 is the slowest you can use which rules out using with of the zooms with less than 120 watts of light..
6) If you want a shallow DOF indoors, you can NOT use the 16mm wide! You need to buy a F1.8 50mm lens. You need magnification to help with decrease the DOF. Which means the camera needs to be placed further way for the same angle of view.
7) With a VG10 because you can set the shutter speed you can start there. But, I teach that it is usually best to set the aperture first. That's because doing so forces you to think first about DOF which is a CREATIVE choice.
Once you make this choice, its fundamentally just numbers.
And, that explains why the cheap NEX works because you can only set aperture. In fact, the NEX-3 with two lenses is practically being given away. The money you save can buy you a fast prime a long zoom. Which when I think about, means that when you buy an interchangeable lens camera you need to reserve the money to buy more lenses. The kit lens is not going to carry you far.
Marcus Durham March 11th, 2011, 03:49 PM Anyone using this on their VG10 via an adaptor?
I'd been after a wide lens for a while after being seriously disappointed with the Sony 16mm (small size aside, it's totally failed to excite me).
I had an eye on a Sigma 10-20mm but I heard several reports that the build quality wasn't up to much. So I went for the Tokina 11-16mm X116 Pro DX (Nikon) which arrived yesterday after seeing some good reviews.
Took it out for a quick play today. Very impressed. It is wiiiiide and sports some lovely build quality. A proper focus ring which you can rack perfectly every time (are you listening Sony?) and at F2.8 it's faster than the Sigma.
OK so it's big and heavy but it's a nice piece of glass that opens up all sorts of possibilities. Line up an interesting shot and start panning and the movement is wonderful. Operation is unfussy, the only downside is that you have to make do with the aperture adjustment on your adaptor which in my case isn't terribly refined. But it works though.
If you get right up close to your subject you can get some lovely images. Although naturally the lens exaggerates perspective so it needs to be used with caution (it's easy to make things look very far away!).
There's no magnification with this lens so you get the full 11mm onto the sensor.
For me this lens is what the VG10 is about. It'll get me shots my other cameras cannot manage and really brings something to the party
Ken Rockwell has done a nice write up so I'll direct you there as he has all the technical info and seems to like the lens: Tokina 11-16mm Review (http://www.kenrockwell.com/tokina/11-16mm.htm)
I won't post any images as the light was terrible today but there are loads of photos online taken using the camera and it acts in video mode exactly as you'd expect.
Glen Vandermolen March 31st, 2011, 09:42 PM Does anyone have one of these a-mount lenses on their VG10? Specifically how it compares to the stock lens.
I'm thinking of getting one.
Steve Mullen April 6th, 2011, 12:33 AM It's got a much nicer long-end than the Sony 18-55 at almost 150mm and a bit wider too. How fast is it? Hoe expensive is it?
55mm is simply too short for me. And, I found the 18-200 an unpleasant lens to use. Sony, IMHO blew it. The camera needs a 16mm to 96mm (6X) with a constant f/4 speed.
Henry Williams April 7th, 2011, 01:46 AM I did a test with my VG10 and this effects lens at dusk. Results below. Not sure if the effect produced - the lens dosen't have an even focal plane - is for everyone, but personally quite a fan.

Heath McKnight May 3rd, 2011, 02:27 PM Sony NEX-VG10 HD AVCHD Camcorder (http://www.kenrockwell.com/sony/nex-vg10.htm)
Rockwell, besides being a great photographer and writer, used to setup major studios' networks, especially for film editing on Avids and the like, so it's interesting what he has to say.
Highlights:
"The Sony NEX-VG10 is a large-sensor, interchangeable-lens HD camcorder. It can also stand-in for a 14MP DSLR for still shots. It's a real big-sensor HD camcorder, and an interchangeable-lens NEX E-mount still camera, all in one. Better than camcorders, zoom is direct with a zoom ring, not motorized.
"The funny thing about its sensor is that it is the same size as 35mm motion picture film! If you're shooting 1.85:1, you're shooting 24 x 13mm, and in 16:9, this camera shoots at 23.4 x 13.2mm. It's the same size as masked or 3-perf 35mm film.
"It records on SD cards, class 4 and faster. It makes great video without the panning defects common to DSLRs, and it makes still images handling like the Sony A55."
Lowlights:
"It does 29.97P only. It can't do 24P or 23.976P for serious cinematography. It doesn't do 60i for fluid motion for sports as most people expect from video.
"The NEX-VG10 has no instant manual-focus override, nor does it have a manual-focus mode switch. You have to flip-out the LCD, navigate menus and revert to the manual-focus-only mode the hard way!
"The NEX-VG10 offers no manual focus aids. There is no monitor zoom or anything else to help you nail manual focus other than by looking at the same monitor you always do."

Dustin Moore May 19th, 2011, 10:27 AM Is it possible to get the LCD to display expanded focus while an NEX-5 is recording?
I searched all around but I can't quite find the answer. Thanks,
Steve Mullen May 19th, 2011, 11:22 AM You want the magnification to remain on? yes it can.But you'll be framing without seeing the whole image. that of course is the advantage of peaking. One needs both options.
Piotr Wozniacki June 18th, 2011, 07:52 AM What is the crop factor of those lenses when using one of those many FD->NEX adapters available, on the APS-C sensor NEX cameras?
In other words: what focal lenth would e.g. my 50mm/F1.4 be equivalent to?
Steve Mullen June 20th, 2011, 12:27 AM When you shooting video the Crop Factor (multiplier) is 1.8.
Colin Rowe July 9th, 2011, 05:38 PM I have a Nex-5, a collection of Olympus Zuiko OM lenses and a Fotodiox Nex to OM adaptor. Am I correct in thinking that there is no full manual control of exposure when using these lenses on my Nex-5 ? I can shoot exactly what I see on the LCD when in P mode, but of course the shutter speed varies as I adjust exposure. In manual mode I set the exposure, and shutter speed to 50, but when recording starts the image dims, and as I understand it, I can only adjust the exposure compensation after recording has begun. With the 550D I record exactly what I see on the LCD, not so with the Nex-5
Henry Williams August 21st, 2011, 11:03 AM Some interesting developments, firstly three new e-mount lenses including a zoom and two primes:

Steve Mullen September 9th, 2011, 03:30 PM I learned earlier this summer that JVC was not going release a camera at IBC as I expected. But this video shows only one of the 4K2K camcorders -- the HD100 looking version.
Interesting comment on editing with FCP.

Steve Mullen September 10th, 2011, 03:03 AM I just earned something I want to pass on.
As you may know many GH@ users are modifying the camera's firmware. Typically the 1080p24 bitrate is pushed up to 45Mbps.
But someone has set GOP size from 12 to 3 -- which forces them to set the bitrate so it peaks up to 70Mbps!
Why 3 frame GOPs?
He says that he sees 24p AVCHD does not reproduce the look of 24fps film because although MOTION looks right, often the background remains unnaturally still.
Someone else claimed -- as I always have -- that because each Predicted frame is compared with the Actual next frame and differences sent along with encoded data -- upon playback the output frame is always corrected.
But, I think I'm wrong for two reasons.
1) When the encoder looks for pixels that have moved by a certain amount, by definition, it is ignoring pixels that have only moved a small amount. (The encoder assumes the eye can't see this.) So indeed, the predicted frame may well have areas that are the same as the previous frame even though in reality a film frame would show subtle changes.
2) In theory when error information in generated these errors would be detected. But, since I have no idea exactly HOW the error information is created, it is very possible no correction is made.
By dropping the GOP to IBB AVCHD comes closer to AVC-Intra.
This also forces me to see the value of recording ProRes or DNxHD when shooting 24p.
But what about 720p60 or 1080p60? First, remember that JVC has used a 6 frame GOP for 720p30 which may be why it always looked so good. Second, the faster the frame rate -- the less time there areas that have little motion to change much. Thus, frame to frame background differences are minimized. At the same time, fast motion differences a minimized because the time between captures is so short.
Glen Vandermolen September 10th, 2011, 07:20 AM I don't know why you posted this in the VG10 section, since it has nothing to do with the VG10/20, and belongs in the general industry news section, but...
Cari Lewis is HOT!
And I really like the 4K2K JVC concept. I guess there's no purpose in releasing it, as no one has a monitor that can correctly see what it shoots.
Chris Barcellos November 11th, 2011, 08:31 PM Sound can be recorded on the VG20 using the camera's decent mike system. Options with the onboard mic include recording in 5.1 surround.
I typically record off camera, so I was interested how camera would sound with a mic fed into it.
Attached is an .mp3 file recorded with the camera, while I was hand holding a Rode NTG2, fed to the camera with the DXA-4 XLR adapter from Beachtek. Sounds pretty good to me.
Chris Barcellos November 11th, 2011, 08:37 PM Forgot to attach to original post.
Jeff Hinson November 12th, 2011, 04:06 AM deleted...review too biased.
Steve Mullen November 14th, 2011, 01:21 PM Looks like the NEX-7 may be a great, but more expensive, alternative. It has the 5n settings missing from the VG20.
Creative Style:
Parameter selection (sharpness, contrast, saturation)
Parameter adjustment (+/- 3 steps)
Creative Style settings: Standard, Vivid, Neutral, Clear, Deep, Light, Portrait, Landscape, Sunset, Night Scene, Autumn leaves, B/W, Sepia with +/- 3 steps of contrast, saturation and sharpness adjustments
White balance: Auto, Daylight, Shade, Cloudy, Incandescent, Fluorescent, Flash, C. Temp 2500 to 9900K, C Filter G7 to M7 A7 to B7, 15-step, Custom
It has a stereo microphone jack for Sony's ECM-CG50 Shotgun and ECM-ALST1 stereo microphones.
Assume it likely has an audio level control.
Jeff Hinson November 19th, 2011, 12:16 PM YEP....may be just the ticket.

Chris Law January 7th, 2012, 06:10 PM Anyone know whether that bag is worth the money or is it overpriced and should I just go for a cheaper one, Im not going to be carrying anything apart from the camcorder and maybe a few lens and a power adapter.
Paul Wood January 9th, 2012, 11:53 AM Chris,
I bought this bag a few months ago - whether it is good value for money is not for me to say, but it is very well made and excellent materials. I use it now as my main bag for my NX70, as I can fit the camera in ¨ready to to go¨, in addition to spare batteries and charger.
The only thing which is superfluous for me is the tripod flap on the top of the bag.
Let me know if you want any pictures with the VG10 in the case.
Chris Law January 13th, 2012, 11:19 AM Hello, I haven't had my camcorder for long so im not aware of the most useful settings to change on the camcorder, are their any settings that automatically are not very good and I should change?
Thanks!
Chris Barcellos January 13th, 2012, 11:36 AM My rules for my own purposes are:
1. Do not use Cinematone, or whatever its called these days. It will seems to add to cause more issues in post color grading.
2. Set your zebras at 100 percent. That will tell you what portion of the image is going close to being blown out.
3. I try to get everything into a manual mode. For about 95 percent of shots, you want a standard shutter speed 1/50 for 24 and 25p, 1/60 for 30p and 1/125 for 60p.
4. The lower the Fstop, the shallower your depth of field will be. If you are shooting outdoors and you want to use a shallow depth of field, get ND filters or a variable ND. Its really the only way you are going to move the lens to the lower depth of field without blowing out the image.
5. In fast moving situations, set your white balance to indoor or outdoor depending on where you are shooting. If you have time to manually white balance, do it, using a simple white board.
6. Try to manually set sound, unless you can't ride it. Then, you should probably leave it on auto. It will be more of challenge in post to clean up, but you will not loose as much. Its a tough call on any on camera mic. I think this one is good, but it picks up camera noise, so consider a separate shock mounted mic still.
Ryan Douthit February 16th, 2012, 11:32 AM Good morning,
I'm in the process of shopping for a B-Roll camera to pair to my NX5U (and later an EX1R or equiv). This camera will have multiple applications, including riding on an in-car mount and sitting on a tripod in desert, wind, rain conditions (with a cover, of course). I have a couple questions that I was hoping VG10/20 owners may be able to answer for me.
Application #1: Car Reviews
I do ride-and-drive events for my own series and need a camera that is lighter to travel with than my NX5U, but also can ride a light in-car mount (and by light, I mean a Filmtools kit with two 7" suctions, Matthews clamps and a crossbar) and, at the same time, be high enough quality to be usable for low-end broadcast.
I'll often be mounting this one on two suctions cross-braced between a passenger door and the windscreen (with option for a third leg). Will the optical stabilizer manage this without "chatter" on all but the harshest bumps? I have an old Canon HC10 and though we can make do with it on baby-smooth pavement, even the slightest roughness in the pavement makes the picture fall apart. I'll likely use the 16mm 2.8 lens in this application (or possibly the 18-55). If I can set the exposure to face detection (reliably) and lock the color, that would be an extra bonus.
Application: Motorsports
One thing that attracted me to this camera - in addition to the swappable lenses - is the ability to do 1080 at 60p. I shoot a lot of motorsports for various car makers and need the ability to slow shots on occasion. Here's an example of what I do: Ford Octane Academy - YouTube (http://youtu.be/dk7qazXUhEM) (I did the rallycross and truck shots in this particular commercial). The "money shot" of the truck jumping (1:01) was done at 720/60p with the NX5U. Anyhow, back on point, I want a b-roll camera that I can mostly set and forget for 20 minutes to an hour at a time. I'll likely lock it down to aim at a particular jump or corner then just start it before the course is hot. I've read that the VG20 has some unusual quirks. I want to start shooting at 1080 this year, and if I do that my NX5U can only do 30p. I'd like the VG20 to fill in the gaps, provide some slow-down effects and also be a backup camera if the NX5U has any issues on location. I have a XLR to mini adaptor with levels and my Sennheiser wireless system has a mini-plug adaptor... so the sound shouldn't be an issue. When it's running as a b-roll, I'll be using the built-in mic predominately (with a dead cat).
I know that's a lot to go over. Any input from owners would be appreciated. I'm not considering the NX70U at this time because I really don't want to spend more than $2k on this second system.
Bob Hart February 18th, 2012, 10:42 AM I quote from a friend and colleague who works as a visiting contractor with high functioning autism spectrum disorder kids and teens using video cameras in social roleplays. These include the device of controlled action drama, which the participants devise if capable or act out from prepared script if not.
Currently they are using small handycam style camcorders but would like to add a little production value without the management of the tech becoming too demanding or distracting from the main task.
A replacement camcorder is being researched. It needs to be able to be set and forgotten as an observational tool, capable of being used creatively for workshop drama but simple to operate and finally to be used in another situation in real low budget film-making and auditions.
Here's the question and hopefully anyone who can constructively comment will be appreciated for their responses.

( name deleted for professional confidentiality reasons ) but what do you think Bob ? and I really dont want a 7D, I want something that will just shoot good footage without the tech side of the 7D
Bob Hart ( reply )
I haven't had my greasy hands on one of the new generation single chip cams from Sony. I'll do a bit of reading and ask a few questions on dvinfo.net and get back to you or you can track the responses.
I think there may be an issue with older editing softwares with the new codec ( recording system ) it uses, which is why I need to check before I get too clever in my comments.
From what I can see, it will be a 35mm sensor camera which will confer a film-style look to your projects.
It will require a bit more techie management than your existing cam but I think will have a more familiar feel to use than the 7D.
It will not be quite as set and forget as the existing cam. You may need to manage light in the venue more diligently, which is I vaguely recall is something you intend anyway.
What "interchangable lenses" it uses, I would also need to look at.
They may be Sony's own ( Minolta derived ?? ) or there may be mount adaptors which allow stills camera lenses like Nikon and Canon to be fitted.
With the larger sensor, lens focus may require more diligent management than the small cams you currently use.
You need to toss up the easy utility of your existing cameras versus the closer to filmic look this one will confer and the distraction that managing it may impose on you.
The filmic look may in itself be attractive to some of your course participants.
Others may resist the increased visual attention selective focus will naturally direct at them in the replays of groups when focus is pulled to a selected individual.
This in itself it may present an additional conditioning or desensitising tool the program can examine and integrate.

John Vincent March 2nd, 2012, 11:57 AM Seeing some videos and threads over a vimeo regarding a weak tripod mounting plate/baseplate fro the VG10/20. Anyone here have any issues with this? Someone suggested using JB Weld (I'm assuming under the original baseplate).
I just bought the VG20, so any info I can get before I start strapping on the glass would be awesome...
Thanks!
Sort vid of making a template for a new baseplate:

Dirk Pel March 5th, 2012, 06:02 AM The video was from me.
I made this baseplates from 1mm aluminium, not a big problem. The only problem was to find the small screws. Here in Germany no problem but perhaps in the USA?
I show in the short film how to find the holes. I have both the VG10 and the 20, after the new plates I'm sure that the original baseplate will not brake away.
There were als baseplates sold by ebay in the usa.
The holes for the 10 and 20 are not the same.
John Vincent March 8th, 2012, 10:24 AM Well, I've a little more time w/ the VG20 and have some more observations:
- This camera is infinitely easier on batteries then DSLRs (or older video cameras). The camera comes with one NP-FV70 battery, which apparently is Sony's middle of the road power source for this type of camera. It came partially charged, and it took me quite a while to drain it all the way down. The battery life is shown as both a scale and a percentage, not a prediction of minutes left... which is just fine.
- With 2 NP-VF 70 batteries and a NP-VF 100 (the biggest battery available for this camera), you should be able to shoot all day and then some.
- The NP-VF100 goes for like $91 at B&H, an incredible value. My last "true" video camera (the JVC GY100) used batteries that cost nearly $1,000 and would last maybe 3 hours. Battery life on DSLRs even shorter for video use, so having such long shooting life is a blessing.
- Took about 6 hours to charge. Be aware that these batteries can be "fully charge" and "super fully charged," meaning if if leave it in the charger for about an extra hour after "fully charged" you'll gain some top end on battery life.
- I also received a 3rd party battery of the same power which works just fine (some reports of 3rd party batteries not working). This battery called "power 2000."
- It has peaking, an incredibly useful feature for focusing. Sometimes it's easier to use peaking rather than expand focus - particularly in bright light, of it your eyes are tired. Here, the VG20 offers not only different colors (I prefer red), it also has 2 levels of sensitivity - another nice feature. Most higher end cameras have this ability and it's a huge plus for this camera.
- Seriously, the peaking mode is nice.
- Screen grid overlays - not terribly useful here, as there's only one option, essentially breaking the screen into 3rds. Not TV safe overlays or the like.
- Histogram - another pro feature this camera has. Didn't play with it too much, but it's available and seemed to work fine. I tend not use them, but to some shooters it's an absolutely needed feature.
- Manual control - on the side of the camera is a "manual" button and right next to it, a wheel. You can assign one dedicated feature to the wheel (such as iris, whit balance, gain, shutter, etc), just spin the wheel and the value goes up or down accordingly. To use/access whatever control isn't already dedicated, just hold down the manual button and the camera puts the user into a menu allowing for full manual control (except for sharpening and contrast).
- You can only use/set these advanced manual modes (as well as mic/sound modes and cinetone setting) if the camera is set up to shoot/record.
While you can access the menu play in playback mode, you can't actually change any settings - apparently a way of preventing accidental changes. Sort of counter-intuitive really, but once you realize what's happening, it's no big deal.
- Using the wheel in conjunction with the touch screen, I found that I could get to any place in the menu very quickly. Again, some hate the touch screen, but I'm coming to like it quite a bit. Def faster then Canon DSLRs in which you must scroll through lots of stuff to get to whatever you're looking for.
- Of course, touch screens are more fragile and not so good in freezing weather, but in the end it does make it easier to get to what you want faster under most shooting conditions.
- 13 hrs - that's how long the VG20 can record straight according to the manual. Obviously, that should be long enough for practically any application.
- Playback - it's very easy to set the camera to playback everything on the card, w/o having to continuously hitting play - a very nice, simple, idea.
- Cinetone - The only other setting available other then "normal" mode. Makes images darker for sure, and perhaps reduces sharpening. May be useful, but I need to do a more detailed examination of this feature.
- 60p - seems to work just fine using 32gb class 10 Transend cards - some had reported that 60p didn't work using 32gb class 10 cards. All I can say is that they seem to work for me.
- The stereo mode works very well. Haven't tried using the 5.1 mode, other than to see if it works at all (it does). On board sound of this quality is a very nice bonus.
- Using an external mic does 2 things: A) it cuts off the on-board mic (which is too bad; it'd be nice to be able to assign each mic to a separate channel), and B) Adds a bit of a delay in the headphones. Not sure why this is happening, but it is a bit annoying. Doesn't affect the recording or ability to judge levels, but it's something I'd like to see in a firmware fix.

maybe couple non fixed shots, i know thre is no IS, and sliders been largely abused by a majority of shooters, but couple slowly moving shots would be nice,
thanks for sharing;
Terry Cummings March 19th, 2012, 09:13 PM The manual specifies the Type V. Type H from an older camera looks identical. Both can be charged with the Type H dual charger and both read the same battery status. Both are Actiforce product line and both have the same capacity and voltage on the lable. Type H will not engage properly in the NEX VG 20. The center index tab on each side is 50% too long. Simple effort with a knife, chisel or Dremel tool would cure that. My question is, has any one done this or does anyone know why it won't work. My guess is the guts are identical, but Sony Marketing needs a change every couple of years to get us to throw out the older gear.
Terry Cummings March 19th, 2012, 09:39 PM I'm getting ready for a major foreign trip. Baggage weight is a serious problem. Here are some of my gear findings.
The LowePro Top Loader Zoom 55 case is a perfect fit if the lens hood is stowed or left off. It weighs 0.8 pounds. The LowePro TZL AW is a bit larger and will take the VG20 with the lens hood in shooting position. It weighs 1.6 pounds.
I found the Sony VCT-80AV tripod works well. It has a remote on the handle which turns the camera on and off and starts/stops the video and triggers the still image when in that mode. It weighs 3.44 pounds with bag. This is about a pound less that my previous traveling tripod. The fluid head is okay. Seems like a good fit for this camcorder. Its rated load capacity is 8 lbs 13 oz.
In the process of searching for this tripod, I came across an adapter cable to convert my older tripod LANC plug to the plug this camcorder needs. Is this change still another Sony Marketing driven design decision?
At home I use other more robust tripods. They don't come with a LANC remote on the handle. Sony I think sells an add on remote, but a trick from years ago comes to mind. We just bought Sony's cheapest remote tripods, transferred the handles to the Gitzos or equivalent and threw the Sony legs away.

Dave Blackhurst March 20th, 2012, 02:56 AM Sony switched the LANC interface to the AV jack MANY moons ago... the RM-AV2 is the smaller separate controller that goes direct into the AV jack if memory serves... I've got a couple "extras" around here that I'll double check the model # when I get to 'em to sell 'em!
