Well canon has Full Frame camera in the 2500 and up just for the body. And they have a huge pro lens selection that goes into the 10's of thousand of dollars. So only nikon comes close to canon in that department.
Now most consumer and prosumer grade cameras are aps-c. And the canon 7D is the top APS-c camera currently. And nikon has the D300s. Pentax has the new K-5. And they are all very good cameras.
Super Frequent Flyer, no joke. Ex Patriot and loving it.
Canon Eos 60D, T1i/500D, Eos1, Eos 630, Olympus EPL-1, and a part time Pentax K-X shooter.
