Unfortunately, my camera is apparently affected as well. Unlike the test shots posted by others I have discovered it while taking a picture during my holidays:
Don't look at the quality of the photo (I know, composition is between horrible and bad). It is a snapshot. But it is about autofocus. The focus point is marked with the red rectangle (thanks to Nikon ViewNX software getting this data was very easy).
The problem becomes visible when looking at the photo zoomed to 100%:
See the person that is supposed to be in focus? She isn't. But the person right behind her is.
I think it is start to perform a systematic test of the issue. I'll use most probably the prescription published on the Mansurovs blog.
Why is it worth doing the test? Well, the photo has been taken using the AF-S mode and I am not sure if the persons were moving at the moment of capture. So I am going to check it in the repeatable conditions.
