Glad another person with an open mind tried the competition and discovered it's worthwhile.
Thanks - it's amazing how many people will bash the brand they don't use on a forum and never try it. With all of the vitriole surrounding the D600 and with the 6D not looking stellar I thought it was time to try it out.
I too am still caught in the Canon user interface paradigm and sometimes wish my D800's controls were easier to locate at times. More time spent with it and it's becoming familiar.
Before I rented the D600 I used it and a D800 in a local shop... I definitely liked the D600 controls more. D800 were even further from what I'm used to.
I DO miss the incredibly good live-view performance of my 5D2 for manual focusing in low light.
The D800 is disappointingly noisy in this aspect altho I found I can trust the focus rangefinder function to be very precise in most lighting conditions with any focus point i select so I can still MF with confidence.
Hmmm - you're the second one to mention that - seems like I overlooked something....
