A few things about the 60D
– I'm told that the 60D will NOT be a magnesium body. This would definitely separate it from the 7D.
– The body of the 60D is also slightly smaller than the 50D, but will have a larger grip area.
– The camera will cost $200-$300 more than the T2i
An all plastic body puts it inline to compete with the Nikon D90 segment directly. Though I've read rumors the D90 replacement WILL have a magnesium body.
CR2 stuff here.
