Hi, im planning to shoot with OIS on the 250 instead of a shoulder rig, for some reason alot of people frown on the use of IOS.

Why is that? does it degrade footage? i havent tested it as yet, perhaps i should.. if anyone has used it let me know and do u recommend i use it or is it more of a last option to stabilize footage.


thanks
 
OIS can help, but it's not a magic bullet. One problem is that any movement too great for the OIS to deal with can cause a sudden jerking of the image, which is much more unpleasant than a little movement. Another thing is that it works better on some frequencies of movement than others. Really, you need to conduct some real-life tests so you can get a feel for it's strengths and weaknesses.
 
Ever since getting the 250 three months ago, I've never not shot with OIS on, I might give it a try sometime as I think I have experienced some certain jerking in the footage, espeically in long tracking shots that last 10-15 seconds and I'm almost moving 180 degrees.
 
I use IOS all the time for handheld shots, and it works great. If I try to pan or use any type of movement, you just have to do it slowly. I've never had a problem with it. Best thing is to just take it out and practice and see for yourself. Soon as the cameras back on the tripod I turn the IOS off.
 
OIS for handheld is fine but as others have said be very careful with panning. It works best if you can keep your own movements relatively slow smooth and fluid, or just turn it off when you have a lot of moving or tracking to do. Have to try it out yourself and see where it's limits are.
 
Definitely turn OIS off when using it on a tripod, as that will really lead to the "jerky" behavior showing up. But for handheld, I usually use it, I find it quite usable.
 
I shot a docu recently that was 50/50 handheld and on sticks. Slow pans and tilts with OIS looked terrible if not done slowly. For now I keep OIS off all the time. I tend to shoot wide anyway so a little shake is not that noticeable.
 
I had a similar problem with my hpx170 that was on my jimmy jib. I had quite often some jerky movements...like the image was shifting for a fraction of a second. Turned out the ois was causing the problem.
 
That is expected, the OIS will try to keep the lens assembly stationary. For small movements while you are trying to keep the camera steady that works well, but as soon as you deliberately pan or tilt you will reach the limit of the compensation that the OIS is capable of, and it will "give up" and re-center the lens assembly. Never ever use OIS when the camera is on sticks.
