View Full Version : Which 35mm adapter is right?

I have been lurking ard here n learnt a lot about 35mm adapters. Now the burning question is,there r so many adapters around,which r the better ones for HC1? These r the few I have seen

1. Guerilla 35 (prototype but US$1000)
2. Redrock Micro M2 (US$500)
3. Formatt Matte (UK150)
4. Letus35 (US$300)

Seems like all of em were designed for the larger cameras like Sony FX1. I wonder if it will work well for HC1. Besides that, is it true that using such adapters will result in a reversed image on the screen? They looks kinda tough to handle. Is that why I some of the rigs have additional TFT screens to flip the image to the correct orientation?

yes, the image is flipped and flopped (also known as a 180 degree rotation), thats why people use external monitors to view the images upright.

i know that the redrock M2 will work with pretty much any camera. it most likely will work for the HC-1, im not sure if its been tested or not yet. i can't speak for the other adapters.

That would mean the 180 deg rotation has be edited in the NLE rite? I gotta check how Vegas can do that..shouldnt be a prob I think.

Yes I'm looking at the Redrock as well.I'm just wondering about some comments I saw at Guerilla forum claiming that this device can lead to some ghosting..

I did not test the MPIC (the fifth choice) on HC1 but the 1/3" CMOS is the same as DVX100A (3x1/3"CCD). I can only guess the lens design covers about the same range, so it should work fine.
Here is a frame from footage (Z1):

From what I gather, Dan's adapter and the G35 seem like the two best. But we shall see soon enough. They both seem to have good light transmission, no "ghosting," excellent form factors, sharp resolution, and good achromats (is Dan even using an achromat?). I have to admit, microwax is my favorite, so I'm probably going to go with the G35. (Microwax produces a beautiful "organic" gamma curve in addition to rich colors and sharp resoution, but it also means a static adapter so there may be grain.) The M2 looks okay, but the bulkiness, motion artifacts, and ghosting seem to rule it out for my purposes, although others may prefer it for its low light capabilities. The L35 has a great design but the macro lens on it is a piece of junk. I know; I use one of the same brand.

Here's an image from the "beta" version of my home built microwax adapter:

I could probably mass produce and sell these (with better image quality than is visible here--sharper edges and less vignetting) for about $70 each. Then again, they're built out of PVC pipe....

And no, that's not "static grain" it's "my dvx produces so much noise when set to outdoors white balance" grain.

Matthew,

The image you posted (as well as others originated from microwaxed screens) is indeed gorgeous. I have made my experiments here using quite a few different types of screens (not microwax but POC which is very close) and I have learned to love them all. (only sin is a bit of vigneting)

Each one can be used on a certain light "scheme" (contrast, low ight, etc) and THIS is the very reason I have gone through hell to make it in such way so one can change the screens in MPIC to suit the light. A refinement (I dare to say) as it always happens with "labour of love" (and no, I do not use an achromat, although I bought one from Century (what a fine piece of glass!... luve it!)

What's a Formatt Matte?

I am using the Letus35 for my HC1. You can read the thread http://www.dvinfo.net/conf/showthread.php?t=49313 and see some of the pictures of the rig and some demo movies.

Dan, I totally agree about different screens producing different results. I like the slightly thicker ones (like I'm using) since they seem to increase dynamic range, but they do so at the cost of needing quite a bit more light. Multiple screens would indeed be a pretty great feature, if you could pull it off.

Sean Seah

Is the MPIC an off the shelf or DIY adapter? I couldnt find much info yet.

Eric Brown

Hey, Sean. Welcome to the forum! A Formatte Matte (box) is not a 35mm adapter. It's just what you said it is, a matte box made by Bogen.
Just a little FYI.

Matthew, how do the thicker ones increase dynamic range? Or do you mean they don't wash out shadows as easily (like the glass ones do), and thus better replicate the range that is out there? To increase dynamic range, either the brights would have to be subdued and/or the shadows would have to get lighter -- all without losing detail. If the thicker wax is somehow doing this, I'd love to know!
As for gamma curve, is this subjective or have you made measurements?
It seems that in the footage from my own wax-adapter-in-progress, the highlights don't blow out like I'd expect them to, and I'm not sure why. The shadows do stay dark, which is nice. Is that what you're referring to? Is it really possible that wax can subdue highlights without darkening midtones and shadows as well? If you are right, then they have an even greater advantage than I'd imagined. Not only are they solving the DOF weakness of video, but also addressing the comparative lack of exposure latitude.
Like you, I'm a big fan of the wax adapters, but am confused by your statements.

Dan, I find your site a little confusing to navigate. Do you mind me asking if you've tested your non-achromat adapter on cameras with 70mm or larger lenses? Are they using macro extensions, then? Is your system exclusively SLR-GG-Video then?

Thanks to you both,

G

a... little? hehehe... the "STANDARD" of "thrown together" gets redefined... (work in progress).

DVX, Z1, XL2 ? Yes!

Yes (and no; I have two UV/dust protecting filters)

Oops!! Ok, let me try to find out more on MPIC. Thanks again!

By the way. My wife is from Singapore. Met and married in Hawaii (where she attended UofH) and now living in Los Angeles.
I'm even thinking of doing a short film in Singapore with a few friends who live there to take advantage of the futuristic look the downtown area has.
I commented to my wife that the city looks twenty years advanced of Los Angeles.
Very cool place to be.

My time back next year in Singapore will be the third time in five years. We will be stopping in Tokyo first. It will be my first time there instead of being stuck in Narita International like the last time.

Exactly. I'm looking forward to shooting Tokyo at night. My biggest concern is lugging the XL2 around. It's a little too big to be inconspicuous.
I saw footage from a Sony A-1 the other day and was utterly blown away by the ultra clean image that tiny thing produced.
The lens alone on my XL2 is almost larger than that little guy!
It has the CMOS chip so no smearing of light.
I'm seriously considering a purchase of one of these before my trip there.
It's interlaced only but when the picture is that nice who cares.
I'm one of those guys who actually likes both 60i and 24p and believes they are both equally viable.
Okay...think we have gone waaay off topic, here.
So, I'll add into this that I'll throw my Letus35mm adapter onto it when I go.
There, back on topic.

G35 is Microwax.

No. G35 may be microwax. They have never said what it is.

Does anyone know if I have to use focus controller to use these adaptors in the environment i.e. steadicam?

my first(actually not so first, because i asked earlier exactly the same thing) question, Winston, is as Donnie Wagner asked in another thread (http://www.dvinfo.net/conf/showthread.php?t=24124), do You have some downloadable footage as well? I know there was DVD containing Your footage but anyway something for network-lazy-people. If You have problem with server space let me know. Because that medium format thing is really damn interesting.

This is the second time (on different sites even) I've seen you put four straight posts plugging your 70mm adapter. While I appreciate the concept of your adapter, I don't understand why you always post four consecutive posts concerning the thing. I would write it off to some sort of computer glitch on your end except that the four posts are always different. Just strange. You're welcome to promote your product, I just find the manner in which you do it confusing.
