    The Canon MP-E 65mm F2.8 Macro. Sometimes it is really hard to take that
    lens off the 5D, but sometimes you need to take pictures of something
    further than 4 inches away, not often, but sometimes. :)

    Do you already have the 100mm macro and find that lacking? If you are
    already doing macro and find the 100 not quite giving the magnification you
    want then try the 65 MP-E otherwise learn macro with the 100 and then
    migrate to the 65 if you need to do so.

    Yes, it is a bitch to use. Hand held it is difficult to steady and on a
    tripod it is difficult to focus, even with a rail. With a steady hand and
    some good technique you can hand hold well between 1X and 3X after that it
    is pretty much a crap shoot.

    It is an awesome macro lens with built-in extension tubes, and a scale on
    the side with both magnification and focusing distance. Let me make this
    very clear - it is a fixed focus lens - at a given magnification it will
    only focus at a specific distance. There is no infinity focus; it only
    focuses between 4" at 1X to 0.8" at 5X. The F stop is very strange :) The
    apparent F stop increases with the magnification. So diffraction affects
    image quality very quickly at high magnification. The DOF is always a big
    issue at lifesize and above.

    If you shell out for the lens you may as well plan on getting the MT-24EX
    Twin Lite Macro Flash for an extra $650 too. If you don't like black as a
    background, an extra 550EX or a 580EX works well as a background fill flash.
    Learn how to use flash diffusers.

    Third image down will give you some idea of the flash & lens set up.

    The Damselfly is at 3X on a 5D and yes that's the full frame with the ends
    cropped to an 8x10 ratio. The tadpole is at 1X with a narrow tank used to
    isolate movement.
    At 1X it is focused ay 4" at 2X it is focused at 2.5" at 3X it is focused at
    2" at 4X it is focused at 1.7" at 5X it is focused at 1.6" from the front
    element. There is no focus adjustment it is a fixed focus lens. Canon
    specs sometimes use the front element, sometimes use the nodal point of the
    lens array and sometimes use the film plane to indicate "close focusing
    distance."
    I used to put all the technical details up, but most people don't care and
    really it won't help those that do care.
    You will probably like the lens, but it will take about 3 months of use
    before you are comfortable with it.
