I got adapter sony and 16-50 . And I do not know what to think . First of all zoom ring is very hard to turn , and in 35mm I feel like is sliding . I do not know how exactly explain it , but I think you know what I mean . It behave like my 18-200 , when I zoom in it does not want to hold focus . So first I have to zoom in and take a proper focus and after that I can zoom out holding focus all the way .
Another thing which I noticed , when I use autofocus it goes to f3.5 ,but actually it looks almost like f4 . I compared to kit 18-200 . Is there any photo lens which give me smooth zoom ring , nice aperture ring , f 2.8 or f3.5 , wide like 18-55 . Which can hold all the time focus ( parfocal ) ????????
