Sigma 50-150mm f2.8 AF Adjustment on K7. How much did you apply?

crossover37 · 05-09-2011, 04:46 PM

The Sigma 50-150mm f2.8 is known to have focus issues and you can either send it in for calibration or use AF Adjustment in camera. I will send the lens in but not for another week because I have two sessions this week.

What amount of AF Adjustment did you apply on your K7 for this lens? I applied +10 and then +0 and still didn't know which one was right.

I think it's better if you go to a Sigma center near you and have the lens calibrated to your body by them.

I just ordered this lens so I'm interested in what you discover.

About how much do you think that would cost?

I adjusted the AF to +5 and it's focusing a lot better. I will probably use that setting until I send it in next week.
