I have read this OIS here and think it is good. How is it good?

OIS or, "Oh it's stable" is better than the digital kind of built-in stabilization. DIS stands for, "disfunctional image stabilizer." Hope that helps. :-))

I just want to add that I always noticed Sony's non-OIS'd cams seemd to have good stabilization unlike my JVCs, though I almost always use an external stabilizer with my JVCs. OIS would be for your upcoming run and gun adventures in and about Edmonton. Ever shoot video in that big mall? Is it still the largest in the world? I read the one in the Twin Cities is larger---don't know if that's right, however.

That is funny Frank. I don't know if our mall is the biggest. It used to be and maybe it still is. Do not know for sure. I know where the biggest egg is.

Glad you liked it. By the way, I know where the biggest mosquito is (a wee town in Manitoba)...I know where the biggest sturgeon is (Kenora)...I know where the Paul Bunyan statue is (Bemidji). OIS is better but few cams have them, and the pro cams don't even have built-in stabilzers. The prosumers use Miller tripods, the pro's use O'Connor's and we use Manfrotto's). I wonder how my MX300 would look like sitting on an O'Connor? :-))

I have a cheapo set of sticks for my K1000. It is no good for video and I do not want sticks for video. I am going to run and gun. I sure like that term. In the winter I am going to run indoors and take a bus to get there, so I will be recording indoors or just shooting with my K1000. Tapes sure cost an arm and a leg. I want to reuse tapes but I do not want to erase footage. Thanks for all the tips.

That K1000, a Pentax? That's a good manual still cam. If you find miniDV tapes expensive, don't shoot so much. :-))

Sony employs electronic sensors (EIS) for their Super Steady Shot (sans optical) and I agree that it appears to be superior to cams using digital image stabilization (DIS) which is less effective and noticeably reduces resolution.

Tommy, didn't the Pana's cams have EIS?
but if i remember when you pan with no subject you have "frames droped" (jurky movement)...

"Pana's cams have EIS?"

My JVCs have DIS. That's why I shut this feature off and use a tripod. (Degrades the video; can't have that.)

DIS - disfunctional image stabilizer
OIS - Oh it's stable
EIS - ?

What about on the DVX100/DVX100a? Leave OIS on for handheld, off for tripod?

That's a good plan. I disengage DIS and OIS when I'm using a tripod.Leave OIS on for handheld, off for tripod?

How about for running?

The marzpak would be bad for running but for rollerblading or skateboarding it's great. I wonder if OIS would help there?

It's better to leave OIS/DIS/EIS on for 'er run 'n gun. I don't run, I do ride a bike, though.

its funny you mention the OIS and tripods., i too have read that you should turn it off., it think they might even mention it in the manual. yes i did read the manual. i was bored and wanted to see if there were any cool functions that were hidden that i didn't know about. but i didn't find anything. anyways i find that if i leave the OIS on i can get smoother pans in a lot of cases however sometime it gets to its limits and then all of a sudden seems to reset itself and you get a big jerk in ur footage.

I press the video recording button for all my video recording because I do not know about how to use all the different things. I have only run and gun once like this and the video looks shakky like a action film look or like on the action news about the war.

Image stabilization cannot correct subject matter ;)

Seriously when the camera is locked down it is OK to leave the Optical Image Stabilization on. This can correct/reduce small jittsers from bumps or wind. Electronic versions of stabilization sense movement in the image on the LCD and try to correct by bit-shifting with the DSP. This can cause moving images to trick the cam into thinking it is moving and will cause the electronic bit-shift to kick in. OIS "Optical" is far more forgiving, and possibly more accurate, but definitely non-degrading to image quality.

Joe, that might be the case for a stationary cam on a tripod but for panning (especially quick) you'll want to have any form of stabililzation turned off.

Also, only digital image stabilization (DIS) degrades the picture but these days there are so many extra pixels on CCDs running through intelligent DSPs thats its barely noticeable in playback (if at all). Electronic image stabilization (EIS) uses sensors to compensate for motion and they do not degrade the picture. I prefer optical image stabilization (OIS).

The following is from a document on ZenerA.com..

The trade off in a pure OIS system is that it can't correct for motion beyond the ability of the prism to move. In a situation like running, (and I do mean running) OIS will give you smooth motion, where as EIS will give you less motion but greater digital artifacts.

Another sort of artifact OIS delivers is when you have a long slow move, like a pan, the prism keeps moving after you stop, causing the very motion you are trying to eliminate. EIS typically is capable of faster reaction times, and while still susceptible to this effect, minimizes the time it appears.

If you are selecting a camera based on it ability to stabilize images you have to consider the type of motion you intend the camera to correct for. If you expect the camera to recieve frequent high frequency shocks, like being buffeted by wind on vehicle mounts...EIS may be a better choice. If you have lower frequency higher amplitude motion, like walking or whip pans to compensate for OIS may prove superior.

If you are planning on running or the like you can just forget it right off. Look at camera stabilization systems like Steadicam or Glidecam.

thanks for that tommy that is exactly what i was talking about. a little shake in panning is better i think then having a big jerk in the middle when the OIS prism gets to its limits and goes back to normal. it does help tremendously for small shakes from wind etc especially when i have my 2x on. I think you just have to find a compromise. the tripod i use is my dads which is a manfrotto 055 like franks. even that tripod gets the shakes at times and as far as prosumer gear goes that is reasonably solid. Dad uses a broadcast camera on a miller and even a larger manfrotto and that too gets shakes from wind so i don't know. do you forget its there and just add it to your footage. i'm very fussy and i wouldn't include some work that you see in documentary's etc but it does seem to work for them. mostly you forget about it or don't even realise it and it doesn't matter.
