So I have recently bought a Nikon D4 which I have been immensely impressed with it. However, two weeks into using the camera the auto focus function wouldn't engage using the my Nikkon 24mm-70mm lens. I initially thought it was an issue with the camera settings but after spending several hours of "fiddling" and having no luck, I tried it on my 24mm lens. And to my surprise the AF worked brilliantly. Swapped it back to the other lens and the issue occurs again. The 24mm - 70mm lens is also very new so I don't understand whats going on. M/A & AF is all on as should be...anyone got any ideas?
