Some people mentioned this lens if someone asking for good 28mm lens. This is reason why I want to try it. I'm already have Schneider Curtagon 28/4 which I think the best 28mm I ever have.Curtagon is more expensive than this lens.
Other 28mm I 've tried are:
Leitz Elmarit 28/2,8
Enna Munchen 28/3,5
Vivitar/kiron 28/2,5
Tamron adaptall2 28/2,5
Enna Munchen 28/3,5
Pentax SMC 28/3,5

There're only tamron and curtagon left to compare with this hexanon. I guess its better than tamron, looks as good as curtagon, here comparison of Curtagon & this lens
