Hi,

Most of my pictures are out of focus when I shoot with a wide aperture with my 85mm 1.8 on a 70d.

I focused on the eye with single point AF.
Did I move too much? Or does the lens have front-/backfocus?

f1.8 1/2000 iso 100

thx for your help

Shooting at F1.8, depth of field is approximately 0.8 feet. And shooting at 1/2000 sec, would freeze any movement. Anyway, after viewing at 1:1, no part of the image is in focus.

You claim, that you focused on the eyes, but the eyes on the right side of the image, meaning that you recomposed. Also not clear, whether you were using AF-S or AF-C or something else. It appears, you may have focused elsewhere inadvertently, or you camera is screwed up.

99% of the time, it is operator error.
