As I have pointed out in my D600 Review, I am quite pleased with the autofocus performance of the D600. It acquires focus quickly and accurately in most situations and in my opinion works more reliably than the AF system on the Nikon D7000. This past weekend I had a chance to do a much more demanding test on the D600, photographing Colorado wildlife. I wanted to see if the Nikon D600 would be suitable for photographing sports and wildlife, since many of our readers have asked me to do that in my review.
I started out photographing birds first. Small birds can be tough to photograph, since they move constantly and they fly fast. My primary subjects were Clark’s Nutracker and Steller’s Jay – both were very active, so they were perfect for testing the speed, responsiveness and the reliability of the AF system of the D600. I started out in AF-C mode, Ch release, Dynamic 39 points and Focus Tracking with Lock-On set to 3 (Normal). Focusing on perched birds was very reliable and I got a lot of keepers. I even used other focus points in the extreme corners while composing my shots and the images came out in perfect focus. However, the moment a bird would take off, I had a hard time tracking it in flight with my Nikon 200-400mm f/4 VR (hand-held), since they were too fast. Very often they were too close and too fast, which made it harder to get anything in the frame and in focus. Gladly, I was not the only person having this problem – Tom was standing right next to me with his Nikon D4 and Nikon 500mm f/4 VR and he was having similar issues. So I knew it was not the camera at fault.
