I have mostly Canon equipment including 5D and several APS-C bodies. I also own many L lenses and third party lenses. Last year I bought a D800 because there were no improvements made to DR of the Canon FF bodies. I also bought the Nikkor 14-24 to satisfy my landscape desires. The Nikon DR is much better than the Canon, no doubt about it. Though I still haven't sold my Canon gear, I've got to say I like the Nikon performance and ergonomics, and I've only touched the 5D once since then.
