Edit: Used the term OIS incorrectly, figuring it applied to ALL forms of image stabilization and not just lens-based. I meant digital shake reduction in camera. Apologies for the confusion.
Just shot some quick video today of kids at church answering some questions about VBS. I'm putting this together for a small segment to run during a future service.
Was using the K1 and the Sigma 70mm Macro. I didn't think to check if OIS was on (tripod mounted), but assumed it would not be since it's video and the subjects would be expected to move anyway, right?
Anyway, when watching the playback I noticed the oddest thing. The backdrop behind the kids would move. There was no AC or blower going and when I checked it during the shoot, I saw no motion. But it appeared on screen, the lines in the backdrop swayed some from left to right or right to left as the kids were just talking (and naturally shifting subtly on their feet).
It's not a problem and won't impede using the video shot, but I found it interesting. Only thing I could think of was that the OIS was compensating for the child's sway and doing some sensor shift or something, resulting in this apparent motion?
Had I been able to blur the background a little more with distance (room was a bit small) I probably wouldn't have noticed it.
