Hate to admit it, but I have the AF issue. Going to make a case with Nikon. Any advice?

Re: It is very difficult to have a serious discussion with someone who is...

As I've said, this shot has been made with a 85mm at 1.8. The width of the picture posted here is about 10 cm. The angle of view on a Full Frame camera for a 85mm is about 28.5 deg. Therefore, for this kind of shot, the focusing distance would have been 20cm. First, the 85mm can't focus at this distance. Then, at f1.8, the depth of field would have been of 0.3 mm ! Even at f64, the depth of field is no more than 1.22 cm, way less that what is showed here.

And you don't need all that maths to realize that this can't be the full picture. Just a very basic experience of what depth of field is tells you that.

And you spend your time telling people are wrong?
