A couple of tidbits this morning about the Canon EOS 7D. It appears there may be a firmware release already and some users are reporting pattern noise at low ISOs. Of course, you should take some of these issues with a grain of salt until more units are out in the field. I don't think there are any major problems reported yet.
This thread over on photography-on-the.net has some very interesting (and way over my head) discussion about a possible pattern noise issue with the Canon EOS 7D. There's also discussion and examples on this post by Martin at MarvelsFilm. Now, just to post the other side of the issue, this post on dpreview forums seems to indicate that the 7d is better than most. And this post also discusses similar issues with the 5D2.
Stuck frames like on the 5D2?
in this post (also on MarvelsFilm), there is discussion of dropped frames (which we see on the 5D2 when in auto):
“The camera drops frames. Period. You already see it during filming; the picture hampers, stutters sometimes. I thought this was due to processing speed of the display, trying to keep up with the datastream in a low-priority mode of some kind. But, alas, once viewed and eventually rendered in FCP the problem is still there. Just a frame here and there. If it wasnâ€™t for the HD, youâ€™d think it comes straight out of a telephone camera.”
It is also mentioned in this post on cinema5d
canonrumors.com is reporting that some new owners (ha – aren't they all new owners? camera's only been out a week or two) are reporting their cameras have firmware version 1.0.9 where others report the first version shipped was 1.0.7. I haven't found a download site yet, but some reports indicate that the camera shops can get it.
