What do you guys think about the new sony option?
"So, what about the A850? What does it give up compared to the A900? The answer is surprisingly little. The frame rate is reduced from 5 FPS to 3FPS, the viewfinder shows 98% coverage rather than 100%, there is a very slight difference to the body's metal finish, and the $30 remote control that comes with the A900 is an optional extra with the A850.
That's about it!"
