That is something I can't help with from here, of course, and it can happen indeed. One question, though: I assume this happens with all of your lenses?



Kind regards, Wim

Hi Wim,

I thought it was just the 12-24mm at first, as that was the lens I tested first, but I'm pretty sure it's all of them now (as per my [url="http://forum.photozone.de/index.php?/topic/1426-nikon-12-24mm-af-back-focus/page__pid__12759#entry12759"]previous post[/url]). I tested the 50mm and 85mm and got poor results at the intended focus plane unless I adjusted autofocus pretty much to the limits of fine-tuning. I say 'pretty much' because, frankly, I found it difficult to tell once I got to about -17, -18.



I phoned Nikon and one of the staff said it was far more likely to be the body in this scenario... plus, I did drop the camera in the summer so I wouldn't be surprised if something in the AF mechanism was knocked slightly out of alignment: I just hadn't noticed it before testing or had attributed out of focus shots to my technique... and I didn't know I was working with such shallow DoF before this post..!

Best wishes,

Ian
