I just traded in my Canon XSi for the K-7, and so far I'm very happy. One problem, though, is that I seem to be getting a lot more noise in low ISO settings. I tend to shoot existing light or use fluorescent continuous lights (5100k temp). I try to keep the ISO at 400 or below w/a tripod, but it still seems like I'm getting more noise at equivalent settings.
I'm an old-time film guy still getting used to digital, so by no means do I claim to be an expert.
Is this just a low-light thing or do I have some cockeyed settings? Or am I being too picky? Here's a sample at 100% - RAW saved as jpg w/no post.
Also, this is a manual focus so it's soft - that's another problem, for another thread.
