Well I just got to use it for only two weeks. During that time while there were a LOT more photos to sift through for post, I personally didn't find that the extra images really gave me any better selection than what I have obtained with the 5DIII at 6 fps. This is purely subjective to the photographer and varying subjects may offer better possibilities at 12fps. It just didn't offer me anything more other than extra photos that I couldn't use.
Quote12 fps does not really offer much. Sounds nice in theory but for wildlife I think it’s excessive
is it !!
Because of the 10/12 fps I have more pictures to choose from a burst of 10/12 fps.
