I have sold my 5DMkII and bought a second 5DMkIII. No regrets. Now both of my cameras are the same model so no thoughts in choosing.
In addition when you shoot with both cameras the controls are the same and this is a plus.
I would suggest to upgrade if you can afford it...
this is what I was going to do…(i'm working enough now and i can afford another 5dm3) but I think there is something unique about the 5dm2…(on some jobs I use an old film camera for the same reason…there is something still very unique to me about film)….getting back to the 5d mark 2…I think it works well as back up camera and has a unique image..??
thanks to everyone at the forum for your replies…!
