    Got a new set of Kenko extension tubes!!

    [​IMG]

    Here are a few pics to show the difference with them. They were taken quickly.

    1) 50mm f1.8 no tubes

    2) 50mm + 12mm extension tube

    3) 50mm + 12mm + 20mm extension tubes
    [​IMG]


    4) 50mm + 12mm + 20mm + 36mm extension tubes

    The focus was off a hair on that last one as I had to manually focus.

    I'm pretty stoked about the tubes and now I have to learn how to use them to their full potential.

    Cheers

    1 question?

    are them the results straight from the camera.... or have they been zoomed in digitally after?

    sorry but being a newbie, ive never heard of these extensions before... but they sound just like what i need.

    i want to be able to take pictures really close... of flowers and insects etc. they look great :)

    what extension tubes would you recommend for the D80?
    scrub that last question ... just found them on ebay, same as yours :)

    I am pretty stoked!!

    Here is a pick i took with them earlier today: http://www.thephotoforum.com/forum/showthread.php?t=77398

    Red Devil UK, they are pretty much straight out of the camera. After the Raw conversion I sharpened them a touch. They are full pics, no crops at all.

    Cheers

    I am currently looking into macro stuff, and I am not sure what to do.
    Still deciding between an actual macro lens, and these tubes.

    These seem very useful for the money.
    How do they effect the lens performance?
    Do they make it less sharp? Let in less light?
    Do you still have the Aperture control at least?
    How do they effect the minimum focus length? Shorter, Longer?
    I would assume you need to manually focus, which is fine.
    But it seems the lens you have on them would no longer be talking to your camera?

    Hey xfloggingkylex, I didn't check the exact distance from the front element, but it was probably around 1-2cm from the flower. I think if I use a longer lense then I can get further away for the same results.

    jtice:
    They don't affect the lense performance as there is no glass in the tubes to refract or change the image.

    The sharpness seems the same, but as you add tubes you get less light in, so in some low light situations you have to manually focus, even with a fast lense.

    The aperature control is still done through the camera, as these tubes carry the electronics through to the lense. You can get really cheap tubes with no electronics at all, but you loose all auto controls of the lense.

    The tubes shorten the minimum focus distance. Each pic I took above was at the closest distance I could get to the flower and still focus. With tubes you do loose the ability to focus to infinity. For my purpose that doesn't matter.

    You can auto focus, as long as you have enough light for the AF to work on your camera, and yes the tubes talk to the camera.

    Let me know if you have any other questions.

    Cheers
