The K-5 (and K-r) is now in stock at both Don's Photo stores in Edmonton (one store in Winnipeg has it too). Each Edmonton store only has one K-5 apiece at the moment. If any Edmonton PF user would like to pick one up at the west side store, PM me for details. (I work there)
I only put about 30 test shots on it, mostly at high ISO, in jpeg and RAW for my own testing. When I get home. I'll probably put up a few samples on Flickr. If anybody would like a RAW file or two to play with, I'll provide those on request in PM.
I'm loving it, can't wait to replace my K-7.
