new lens back focusing problem
i never had this problem before. i had the 18-55mm kit lens, it focused fine. and then recently bought a new sigma 18-250mm lens, and suddenly i'm getting soft photos.
i lately realized it wasn't a lens quality problem, it was back focus.
when i'm shooting portraits for example, i keep a focus point on the eye, but what i'm getting in focus is an ear or something!!
this is persistent in every focus mode, and at all focal lengths.
i think its getting worse with time, it started with like 30% of the shots, now its like 90% is OUT OF FOCUS SHOTS! what do i do guys, help me.
