    Default Lens Performance

    Hello Just A query
    Is there any difference in terms of picture quality between two lens with similar setting?

    i.e
    using lens 18-200 and 17-55 whats the performance on similar setting
    let's say @ 55mm f9
    this is with the assumption everything is similar.

    Of course there is.
    - the construction of the lens elements is different
    - Optics quality is different
    - lens coating plays a part
    - number of aperture blades used might be different
    not to mention the camera used
    Take the shot!

    Oh that says it =)
    I have tamron 17-50 2.8 right now,
    and WAS planning to buy 18-200, and dispose my tamron already, apparently I wouldn't
    I'm fully satisfied with my Tamron right now =p

    You could just have looked up the reviews of both lenses and seen the comparisons?

    You do know the 18-200 dosen't have a fix aperture and may find it slow in low light .

    Thats a downside but you can convienience and versatility !

    There'll still be issues like lens distortion, flaring, CA etc.

    Don't ditch the Tamron! I intend to get one soon for low-light shoots. The Nikkor 17-55 is too ex for me

    get both and find out yourself.

    seriously though, i dont' think much of difference between superzooms and kit lens. assuming that you are talking about 18-55 kit lens, that is.

    unless you are talking about 17-55 f/2.8, then i think at 100% crop the 17-55 will be likely to be sharper.

    Definitely at Low Light Tamron will have an edge, but Im looking into a bright sunny day,
    with similar f and focal length.

    Will read those links thanks Man

    You can try this link too.

    I used to own both 17-55 and 18-200.
    At aperture like f9, not much difference. But at f4 and 5.6, the 17-55 is really better.
    But the 18-200 wins hands down on convenience. Both are favourite lens for me.
