What follows is my video demonstration of the issue, as recorded from a live session with my second D800 body. Well I guess it’s my turn to chime in, late as always 😉 More recently Thom Hogan, a respected Nikon shooter, blogger, and author of must-have guides about Nikon bodies wrote about his experience with the issue, disclosing that he’s personally observed it on 2 bodies, out of a sample size of 12 bodies. He even went so far as to visit a Nikon service center to demonstrate the problem in front of Nikon technicians, where they cycled through several samples of the 24G and D800 bodies, not to mention other full-frame Nikon bodies like the D3. To my knowledge the first person to discover and disclose this issue was Ming Thein, a photographer who maintains a blog Here. Those few to a few hundred online threads about this issue have spanned the spectrum from “you’re imagining things” to “you’re testing it wrong” to “mine sucks too, let’s go have a beer and commiserate”. At around 4 feet and beyond the focusing error becomes unusable wide-open on my 24G. The left AF point? It’s a little off starting at MFD (minimum focusing distance), then gets progressively worse as the focusing distance increases. After finetuning this second body with my 24G (-5 AF tune for you geeks), the center and right AF points produce perfectly focused images at f/1.4, over a wide range of focusing distances. The bad news is it’s consistently bad, at least when focusing using its leftmost AF point. The good news is the second body has highly consistent autofocus, just like the first. The first body had perfect AF – its left and right AF points were highly accurate and consistent across all my lenses, including the ones most sensitive to the Left AF issue, the 24G f/1.4 and 14-24G f/2.8. I’ve had two D800 bodies so far, the first I acquired soon after they became available in the states and a newer one I bought within the past few weeks. In today’s blog I’m going to discuss the issue, and then present a video demonstration of the sadness on a recently-acquired D800 that is afflicted by the disease.įirst, is the problem real? Yes.
If you’ve been following the online forums about the D800/D800E you may have come across a few message threads about a “Left AF point” issue.
