Can you tele-extend a 60mm micro Nikkor?

    Hello Everyone,

    I've been having a lot of fun taking pictures of insects and small plants
    with my 60mm Nikkor "micro" lens. Some of my latest pictures taken with
    this lens are at http://www.scottspeck.com/old4/index.html. The blue heron
    pics on that page were taken with a 80-400 Nikkor zoom with VR having been
    activated. All other pics, both short and long range, were taken using the
    60mm.

    My question is, could I use a tele-extender to further magnify images taken
    my micro lens? If so, would this introduce much distortion of the image?

    Thanks for any help,
    Scott

    In message <>,
    My suspicion is that the "90mm or greater" value given by TC
    manufacturers assumes a "full-frame" sensor or 35mm film. With an
    APS-sized sensor, you can probably go down to 50 or 60mm. I use a 1.4x
    a lot with my Tamron 28-75 on my 20D (1.6x crop sensor), and it only get
    a little funny down around 28, and then only wide-open.

    A good tele-extender should not seriously degrade your images. You will lose
    some speed (with a 2x extender you lens will become a 120mm f5.6), but on
    the upside your minimum focusing distance remains the same, giving you twice
    the magnification :)

    Yes you can, but there is a limit, if you use a 2x extender you get a
    120mm f5.6 lens, no more. The one advantage you will get is at your
    closest focus you will get 2:1 instead of 1:1 at the same distance. Now
    for the bad news telextenders always degrade the image, if you are
    starting with a micro Nikkor you are starting with an excellent lens so
    the images will PROBABLY be OK. Don't buy a cheap one either
    telextenders are generally designed with the manufacturers lenses
    (mostly telephoto) in mind. The Nikkor 2x telextender is $300+, you may
    be able to get a faster 100mm lens for that price.
