Re: Try a proper focus test before ditching the lens

Try to focus with other focus point close to the center. It works in my sony a57 with my tamron 17-50 and sigma 75-200 2.8-3.5 so it might work with that (but it doesn´t work with sigma 50mm f1.4 that sometimes just misses with consistency). Sony A77 has micro adjust and then the Sigma 50mm f1.4 works.

Try the for focus point closer to the center point and recompose... (my sony a57 has a tilted AF sensor that is why it works with all back focused lenses to a point, but not with Sigma 50mm, I don´t know why)).
