Thread: How to use extension tube?

    Default How to use extension tube?

    I've just received my generic extension tube. It has no metal contacts with the body as such i would need to manually setup the camera.

    The physical setup is do-able as its kena idiot proof..
    Set the priority to M, aperture f11, using a 16-85 nikon DX lens.
    However, when i look thru the VF, its almost black except for certain area that has light.

    Nevertheless i still try to take a pic and its totally black.

    Tried to google for answers but most just touch and go on this subject without a step by step walkthru.

    Would appreciate any help so i can start taking macro photos.

    Hmmm.... this is weird. Mind showing a picture of your extension tube?

    what was your shutter speed?
    have you thought that it might be your aperture being too small??
    you might need a flash to illuminate your subject to keep shutter speed up..

    im not very sure as i don't shoot macro nor use an extention tube.. maybe you can wait for someone who is more proficient to explain it to you

    The manual extension tube doesn't let you change the aperture, so if you use the normal G lenses, the aperture closes to f/22 or whichever is smallest.
    I suggest you tape the aperture fully open using tab on the rear of the lens before you use the extension tube.
    Better option is to use a non-G lens like the 50mm f/1.8 D.
