Dear readers,
Try to bear with me as I have a strange problem with my Nikon D800... At about 1/3th of the occasions I can't seem to get the focus right. Now AF fine-tune could be a solution, but that were only the case if the focus deviation were to be consistent, which ofcourse it isn't.
Today I tried to focus on a tree which was about 40 meters away. The lens that I used on the D800 was a Nikkor 70-200mm f/2.8 VR I and I shot at f/5.6. At the resulting image the focus was about 20 meters behind the tree! I made the same shot a couple of times to exlude any user error but the backfocus remained. I tried a different tree a little bit further down the road and this time the D800 absolutly nailed the focus. At least I thought it did, because the following shots were all misfocused again. Sometimes a couple of inches, sometimes multiple meters, only to get it right again every now and then. The distance between the subject and me also seems to be of relevance as nearby objects seems to be in focus much more often. At the end of the day I got really frustrated so I tried to correct the backfocus once more with the AF fine-tune. Zero correction resulted in heavy backfocus, as did -5, as did -10 and -20 as well! The funny thing is... Next I switched off the AF fine-tune completely and this time the focus was spot on! Huh?? I have the same problem with my Sigma 35mm f/1.4 ART which I use very often for portrait photography. Depending on the distance (between 0,5 and 4 meters) there is backfocus occuring and I need to dial in the AF fine-tune between -4 all the way up tp -20! This is when I use the central focuspoint. But when I use the focuspoints to the right there is a sudden frontfocus which increases as I select a focuspoint which is furthermore to the right. At the most right focuspoint a correction of +20 isn't enough, so often I reside to Live View, which is absurd ofcourse.
So, now what? I have a few weeks of warranty left on the D800, but Nikon Service only knows one awnser... "The D800 has a lot of megapixels, so you see every tiny fault regarding focus and shaprness." Well, that's not only dump, but also insulting! Heavy misfocus can be seen even on a 2MP camera!
Any suggestions?
