Thanks for the comparison Darrin.
I have a 7D and have just been reading up on whether to make the jump to full frame with the 6D.
The 6D is a clear winner in the lower noise department and higher ISO but i see the it does not have the little joystick on the back like the 7D or pop up flash and a slower shutter speed f/p/sec.
Both cameras have their good and bad points but I suppose i will have to weigh it up.
Cheers Daniel.
