Upgraded my old D5100 to a D610 last week and noticed that most of my shots at wider apertures seemed to be out of focus. I did some tests last night with the camera on the tripod, angled about 30 degrees at a piece of printed A4 paper flat on a table about a meter or so away and the camera and lens combination is consistently focussing behind the selected AF point (center in this case). I can adjust with AF fine tune, but even at the maximum setting it's slightly better but still considerably off. It's definitely not camera shake because some text about an inch further up the page was nice and sharp but the text directly under the focus point was blurry.
The only other FX lens I have is my Sigma 105mm macro so I test that as well and it's fine. I did also test both those lenses on the old D5100, there's no adjustment there but both of them were better than the 50mm on the D610 so it seems to be an issue between the 50mm and D610 only.
What are my options here, is it the lens that might need some attention or the camera, or both? The camera was bought used from MPB.com so there's some warranty there, the lens I've had for a couple of years so I guess I'd have to foot the bill to get that sorted, if it comes to that.
