Sigma 17-50/2.8 OS HSM with Sony A55 focus issue
Apr 8, 2012

I have bought real cheap new Sigma 17-50/2.8 OS HSM and then Alpha 55 to use it (I guess I should have bought A580 instead) and I feel that in some cases the photos using AF are slightly out of focus. On Russian Sony Alpha forum I got an advice to use manual fine focusing after AF is locked which helps. But in many cases it's not convenient or/and possible.

If somebody using this set faced the same problem and found a solution, please, share your knowledge.
