Dear All,

I am trying to find out what went run with my shooting with a Canon t2i, with a EFS 15-85 lens. Here's the testing footage:


If you play this in full screen, you will notice noise in pretty much everywhere except the white area. I shot this with ISO 200, f 3.5 and shutter speed 60. The room is brightly lit with fluorescent lights.

Do you think it's because of the lens?

THANKS!!!

I'm not seeing too much noise. What I see looks more like compression artifacts. I have no way of telling whether that's from YouTube's compression, from blowing 720p footage up to fit fullscreen on a 1080p monitor or compression from the camera's codec.

asa (iso) for video capture on canon should always be 160 or multiples (320, 640 and so on)

It's impossible to be definitive on the basis of a youtube video; you could post some uncompressed stills (in PNG format, probably) extracted directly from the original camera files, and we could be more critical. Or put a short movie clip up somewhere.

But from what I'm seeing there's nothing much wrong with it, at least as far as Canon DSLRs go.
