Thread: Advise needed for lens specification

  1. #1

    Default Advise needed for lens specification

    Always wanted to start photography as a serious hobby finally has the time and $$ to do so.
    By the way can any photo-master-guru out there recommend any good web site where i can read more about those DSLR Lens and which one to use for different occasion

    there may be a lot of recommendations and most will sound alike...
    ...but it really depends on your own taste and inner vision : eg for me i like to shoot portraits at 400mm and to me, 28mm is wide enough for every scene

    go library lah.....

    or try




    theres tons more out there on the web....

    at the end of the day, ask yourself what you want to shoot....theoretically you could buy everything from a fisheye to a 1200mm L, but what do you love to shoot?
