Konovalov, I use a small digital camera, a Nikon coolpix 7900. (7megapix) I can have it in my breast pocket to keep batteries warm in the cold. It also have like a small grip on one side, which makes it ok to hold with gloves. It has great colors outside, but is mostly crap for indoor stuff in my opinion. I would also like it to have a bit better wideview, but in all it works very well and didn't fail on the two high altitude and quite cool trips I have made so far.
Cheers Porphy
