I just got a new lens, a 24mm 1.8, went on a photo shoot indoors with natural light and I noticed that ALL my photos at 1.8 were out of focus. Tack sharp results in front of the subject.
So I made a few tests with a 50mm 1.4 AF-D. Camera on a solid tripod, shooting at a steady subject at 45° at 20" in front of the camera.
1. De-focus the lens manually all the way to infinity. Take a shot and check for focus on the LCD.
2. Same process, this time de-focusing the lens to its closest focus and take a shot.
ALL my shots were out of focus, the most annoying, its not consistent :miserable:. Trying to micro adjust its useless, sometimes it back focus a little, and sometimes a lot. Other times its front focus by a few milimeters, but at 1.4 and even at 1.8 with the 35mm DX its more than enough to make a picture useless.
Manual focusing works fine, spot on.
Live view focusing works fine as well.
Reset the camera to factory did nothing.
Is this an issue with the D7100?? I've seen a few threads that present similar issues with AF.
