I've been using Canon for 12 years. I had film camera, then 20D, 5D, now 5D MK II. Now i am considering to sell my camera and all L-series lenses and switch to Nikon. Never tought it could happen to me! But what Canon is doing recently is just some kind of a joke. 6D is a big dissappoint to me, less mpx than MKII, higher price, no built in flash (I know it's funny but i wanted to use it as a family camera). Canon doesn't have breaktrough developments like in the past, this brand will become follower not leader soon (maybe it is already). The next thing they would announce: "Please customers don't buy Nikon, we will do something worse for much more money somewhen in the future. These rumors about a possibly developments are just trying to slower Nikon sellings. Won't work, Canon!
Never takes long.
