Sigma Telephoto 80-400mm f/4.5-5.6 EX APO OS (Optical Stabilizer)

Discussion in '35mm Cameras' started by Robert Meyers, Jan 7, 2004.

  1. Hello all,

    I was wondering if anyone had checked this lens out? I was interested in
    quality and capabilities? Is the $400US more worth it for the canon L

    Thanks all!

    BTW- Does anyone know if this lens keeps the same length or not?

    I think lens change his lenght passing 80 to 400 mm focal length because
    maximum aperture go from 4.5 to 5.6
    This means lenght changes, lens scheme is front-focus. Zoom with
    Internal-Focus (IF) don't change lenght and don't rotate the filters mounted
    on. IF Zoom have constant aperture, like Canon 70-200 f/4 USM L.

  3. This extends by 3" or so when you zoom to 400mm. The removable tripod
    collar is convenient and solid enough. It's certainly sharp enough
    for personal photos from a tripod. If you are going to make a living
    selling wildlife shots, the Canon may be worth the extra money.

  4. Have you seen if it is quality or not? Or how they compare?

    For a Canon user the extra money is certainly worth it as there is no
    guarantee the Sigma will work on your next Canon body. Sigma will re-chip a
    lens once but only once and in my case they said the lens was "too old" to
    rechip -- the lens was 6 years old. 400 dollars today for a lens that will
    still be usable in 7 years and beyond is my idea of a bargain.

    Not to mention that it is, after all, a Sigma. Every piece of Sigma gear I
    ever bought was trash, and I'll never make that mistake again.
