is this backfocusing/front focusing? i suppose there's a lil backfocusing.. i focused on the black dot.. it's an image of a tree trunk.. captured from upwards
kit lens, cropped.
Handheld? If handheld with shallow DOF, it's not easy to get accurate result.
What I did test before is using tripod or put the body on table or that is doesn't move.
I tested shooting and compare both Viewfinder shot and ViewFinder, the result is consistent no matter how many times I tried, and it's done with good lighting, so I'm using lowest ISO.
The difference is very minimal, the service personnel were not able to tell the difference, but because of too small difference, they won't adjust it and advice to use the in camera adjustment (which unfortunately not available for D5100)
Well, that's when you get very close to your subject and the DOF is shallow. The minor back/front focusing will be noticeable. If you shoot from further distance, then it's less of a problem because the more area will be in focus.
