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

I believe the slight softness is caused by a combination of factors. The extremely shallow depth of field, exacerbated by the hot sky causing flare and maybe a slight misfocus. Also, most lenses are a little less sharp when shot wide open. The Canon 85mm f/1.8 is a decent lens, but in my experience only the center gets tack sharp when shooting wide open.
