Re: Optical Image Stabilization makes a difference
I use to have the same feeling, but now I think different. I tested the OIS on one occasion where I had to shoot handheld, following subject, different angles, fast movement etc, and I could acctualy see the difference!
These "shaking" situations acctualy demand some more expensive stabilizers, but I found the OIS very helpful alternative.
And for skin detail - I really couldn't tell. I never even changed it's setting. I don't even know which setting it's on (I'll have to check) and my picture is great!!!
Cheers

I use the OIS when using my Glidecam. It helps to "forgive" any unwanted jerkiness and enhance the smoothness of the shots.
I also use it when doing handheld shots that I don't want to look like handheld shots
Overall, I find the OIS to be very useful. I'll turn it off, obviously, if I am using a tripod or some other stationary device.

Re: Optical Image Stabilization makes a difference
The OIS was designed for one purpose only, and that was to "assist" us when we are going "hand-held". The only way that I know of to tell for sure if there is any difference between having it on or off with regard to picture quality would be to run scope tests.
One word of advice when using this function and that is "never" use it when doing a pan or tilt on a tripod. It will screw up your picture because the "gyro's" sense movement and then start to compensate for your pan.
The skin detail function in the menu does work and it's designed to "soften" certain skin details. My personal feelings on things like this is leave it alone unless you have a very good monitor and control over your image. Once you use it, you lose the ability to change it back in post.

Re: Optical Image Stabilization makes a difference
The way to see the OIS effect is to zoom in to maximum telephoto and try to handhold a shot. Turn the OIS on and off, and the effect should be immediately noticeable. At wider angles it will have less of an effect, the more telephoto you are the more it stabilizes.
As for SKIN DTL, its effect is very, very subtle. It does work, but it makes just a minor softening difference.

Ok, I know a guy with a Sony PD150 and he does handheld work without any steady cam rigs and his stuff is super smooth.
Is the OIS on the Panny just not as good as the Sony?
I just did a test with my 100DVXA and the OIS is somewhat noticeable when I zoom in on some text on a book. It takes out the minor vibrations but that is it. When the lens is on anything larger I cannot even see the benefit even when shown ona a large screen TV.

Guys so is it recommended to leave OIS while flying glidecam? I heard you should also turn it off when using steadicam rigs.

"Image stabilization compensates for slight movements of the hand during shooting. Optical image stabilization works by using gyros and prisms within the camera to compensate for camera motion"
Perhaps you expect a little too much from the OIS system?
OIS works fine on my DVX100, but I understand the limits, perhaps you're not quite as steady on your feet looking through the viewfinder, or at the LCD as you think. It's very easy to sway without being aware of it when you're concentrating on the shot....do a free standing 30 second shot standing beside a tree/wall, then do the exact shot leaning up against it, then compare. My money is on you moving without knowing it.

Re: Optical Image Stabilization makes a difference
I leave it on and it helps iron out slight jerking movement. It's difficult to get perfectly smooth footage using just a handheld stabilizer like the Glidecam 4000. It's a personal preference but it works fine for me.

Re: Optical Image Stabilization makes a difference
It doesn't really stop MOTION, more so JITTER. You'll notice the movements you get when OIS is on are more swaying, kind of like you're rocking on a boat sort of thing. Jitter is eliminated quite effectively though, the slight, small, jitters.
But OIS is definitely no compensation for a tripod, dolly, or properly operated steadicam.

Re: Optical Image Stabilization makes a difference
I agree. However I didn't have it on this one time when I was at full zoom and with my shakey hands the footage was crap, then I figured out how to press the little button and wham better cleaner footage. I say it does make a difference, but nothing compares to a stabilizer or tripod.
