Nikon is the enemy? A quick look at my signature lines, below, will indicate that I do not consider either Canon or Nikon to be enemies. The one thing that does bother me, however, about the newer Nikons, is the ergonomics. Until the 7D was released, I preferred the feel of Nikon camera bodies, as the Canons tended to feel like bricks. The 7D was a dramatic ergonomic improvement, and the 5D Mark III has followed suit. When I handled the Nikon D800 and D600, I found that it is now Nikons that feel like bricks, are less secure in my grasp, especially where the right thumb rests, and my wrist starts to ache within minutes. (I am developing a touch of arthritis.)
Of course, this is an individual thing, and if one mostly shoots with tripods, much less important. I am considering an eventual D800E purchase, but mostly for landscapes, which are shot with a tripod, and with a remote shutter release.
Then, there is the matter of re-learning the controls. I noticed that the D7000 I bought for my Nikonian wife had some important controls that were different from earlier Nikons. She had quite a bit of trouble re-learning the D7000 controls, after being familiar with the D300s, D300, and D200. This was particularly vexing because she shoots evidentiary forensic images at night, when controls are more difficult to see. Of course, anything new can be learned, but there is going to be a transition period. Folks who study such things say that it takes about 3500 repetitions for an action to become reflexive,
rather than a conscious action.
Personally, I have two 7D bodies is because I know the 7D best, my right wrist does not ache, and I, too, shoot evidentiary images at night. I am grateful that the 5D Mark III largely shares ergonomics and controls with the 7D, so it is more likely that the 5D3 will be my next FF purchase, rather than a Nikon FX. Of course, I am more heavily invested in nicer Canon lenses, too.
I am not recommending either path, just providing some food for thought.
