My third thread asking help in as many days!
Since I bought my D90 is Jan, yesterday was the first time I used it with my 50mm and wide open (wider than f/2.8). Over the course of the day, I noticed that my focus (auto but using various AF points by hand) was rather off when shooting at f/2.8 and wider. Examples below. Now, I've had my 50mm for over a year, so unless it's gone wrong, I am thinking it is the camera. When I went to Marwell in Jan and shot at f/2.8 and f/4 with my Sigma 50-150 and borrowed 70-200, I didn't notice anything obviously wrong, but then, these aren't as wide, so any focussing issues wouldn't be as obvious?
Few basic exmaples, jpegs off the camera directly:
Focussed on head, focus seems a good foot in front; is that even possible? f/2.8
Same again, focus very much on grass in front. f2.8
Focussed on top raisin, not too bad but possibly in front again by a cm or more. f/4
Will need to do some focus tests using an online template and check with my lenses this week, but any tips or advice from anyone, who's come across the same issue? Is it a costly fix if I need to have the camera+lens calibrated and would it be free under warranty? Is it possible for only certain focus points (11 total on the D90) be off?
