It seems you don't shoot video. Shooting at 1/30, 1/60 or 1/4000 does not improve eliminate shake in video, but IS cuts it down quite a bit.
Hand-held video is common even on big budget films today. Eliminating the micro-shakes improves the look quite a lot. The camera on a shoulder brace with a 50mm with IS is great on FF, and even more important on a crop.
No, I shoot lots of video. My point was that IS for video and IS for stills is entirely different because of the contiguous nature of video footage. Most photo lens IS has been designed for photo use, i.e. short bursts of agressive and noisy IS, not prolonged smooth and quiet IS.
It seems you didn't read the second part of my answer. Supported. Could be a studio pedastol. Could be a shoulder rig. Both of which would negate IS.
IS for video is called steadicam. And it works on the entire set up, not just one part of it. I'm not saying that in lens IS can't be used for video, just that it sucks.
Can you tell me one film that you can hand on heart say has been shot with an unsupported 'hand held' camera, that is no rig, no steadicam.
Cheers!
