Thread: Is my lens ok?

    Default Is my lens ok?

    Hi,
    Need some help and comments. Just bought a new lens (Tokina 11-16mm F/2.8). Took some pictures with my D80 and they don't appear sharp as many brothers have commented. Pls advise before I bring it back for exchange. TKS

    Picture on the right is Tokina 11-16mm shot at 16mm F5.6 and
    on the left is Nikkor 18-200mm VR shot at 18mm F5.6.

    Both pics at 100% zoom.

    Just hope I did not buy a lemon...

    Many thanks,

    both pic are zoom at 100%, but ur screenshot is NOT!... unless you telling me u using a screen with 300px as width...

    just to add, if you trying to show something on sharpness, its better to use lesser jpg compression... they make the whole picture looks soft even on a super sharp picture
