Poll- 16-50 SSM problems

I tested 3 lenses to find one with balanced optical performance.

None of them was faulty, the necessary AF micro adjustment on my A77 varied between -4 and -1. Each of them had different optical weaknesses, but none of them I would call bad. The first two lenses were not well enough centered at the long end for my taste, but I have to admit that I am very picky in this respect. I guess for most people the performance would have been acceptable.
