Nikon - Difference between ED and ED-IF lenses?

Discussion in 'Nikon' started by Steve Edwards, Jan 17, 2004.

  1. I'm looking at 80-200mm f2.8 AF lens for taking pictures in hockey rinks.
    I've looked at Nikon web site but can understand performance differences
    between ED and ED-IF lenses?

    thanks

    ED stands for the use of low dispersion glass elements in the design of
    the lens.

    IF stands for internal focus. A design whereby the focusing is
    accomplished by moving a subset of the elements, rather than by changing
    the length of the lens by using a big helicoid.

    In general, an IF lens may perform better in an auto focus camera
    (faster focus due to the lower mass that needs to move and lower battery
    drain, again due to the lower mass).

  3. Any version of the Nikkor F2.8 80-200 pro zoom will work just fine for what
    you want... Lots and lots of published pictures in SI, et. al., with that
    lens... Save money and skip the latest versions <unless the price is
    right> and get a used one of the garden variety... I am adding the 17-35
    F2.8 to my stable, but I see no reason, optical or mechanical, to replace my
    older 80-200 F2.8...

    If I could get a used IF for the price of a new ED, what do you think?

    I believe all of the current 80-200/2.8's are internal focusing.

    I have an older version of this lens and the only reason I can think
    of getting the newer version (IF) is if you don't want the front
    element to turn while focusing. It has about 100 deg of rotation.
    Something that can be rather irritating when using a polarizing filter
    and a hood.
    Mine is the one touch zoom-focus AF.
    I would only upgrade if I were interested in the silent wave motor,
    which I am not.
