I bought this lens along with my camera in stores and was in the first time deeply disappointed by the large number of fuzzy images that it produced. Since I ascends through E-Bay is an old Minolta 35-105, F 3.5-4.5 for a full 60 EUR, I hardly use the SAL 16-105. To check whether the blur is caused by an incorrect adjustment of the lens, I had it with the Alpha 77 in after-sales service, but could not find one fault ... It remains only my subjective impression that the Minolta lens produces sharper images ,
