Canon EOS 7D 18 MP CMOS Digital SLR Camera with 3-inch LCD (Body Only)
I'm not much for writing reviews but for this I had to. Below are the pros and cons I have seen.
Pros:
Auto-focus: Fast and accurate. Distance it is not so good for (ex. bird flying against a background in which they blend in, most cameras have issues with this) but all normal circumstances it performs excellently.
SPEED: 8 FPS, that makes my 5D2 look as slow as a snail. People turn heads when you fire this camera.
EASE OF USE: You can easily customize your buttons. Easily separate shutter from AF of whatever you would like to do. Great addition by Canon.
ISO SENSITIVITY: Though this is what i would expect from any DSLR with this price tag, the ISO sensitivity is awesome. 6400 will give you grainy pics but that is better than completely missing it, right?
Cons:
ISO: As mentioned above 6400 is grainy, I avoid if possibly but sometimes you have to use it. The full frame of the 5D2 trumps over the 7D in low-light performance.
Video: Like the 5D2, I still think the video function is very raw. No quick auto-focus. Do NOT buy any DSLR because it has video on it. Horrible idea. Will not work unless you know 100% what you are doing.
