Also, for those decrying IS on a wide-angle. This is a godsend for those of us that dabble in video and aren't always able to use a tripod/afford-advanced-stabilization. And who wouldn't want to to get some creamy waterfall shots without having to use a tripod? ;0
Em, that would be me then.
I shoot video professionally, and I always use a camera support of some description, these vary depending on the shoot circumstances, some of solutions are 'pricey' like a dedicated video tripod, some are simple and portable and inexpensive, like a monopod or superclamp, for run and gun the cvp sm-1 is proving a minor hit with me, although you'll need a camera with a flip out screen to make the most use of it, and this is very modestly priced. I've always meant to buy a 'pod', you know the bean bag with the tripod screw, and these cost around £8.
IS looks great on the screen because the screen is small. But it can induce sea sickness on a large screen as the frame drifts. Support means supported movements as well as just anti-shake, and unsupported movements (as you get with IS) are often as amateurish looking as wobbly footage.
Each to their own, of course, I've detailed what works for me, and IS just doesn't. Or at least, isn't worth the extra cash when I'm already supporting my kit in other ways (which don't always play nice with IS)
Broad church, horses for courses etc.
