Pros:
Well built.Canon has aimes this at the editorial,magazine photograper.Good sensor size.12 million effective pixels.
It’ll make its name somewhere between the 20D and the 1ds.
excellent ergonmics.
Cons: price.
I use Canon gear proffesionally.And thoroughly reccomend them.
I posted a thread about this camera on the black flag a couple of months ago.in the gear section.
Cheers,
