    A recent thread made me wonder about this. Would I be able to use my 1.4x teleconverter in addition to my 25mm tube on my 100mm f/2.8? I am just asking because I am too concerned about hearing metal hitting glass in the process of discovering by ones self!

    Thanks

    Yes :)
    Order...convertor, tube(s), lens. You can use any different combination of convertors and tubes.

    Actually, there is no real reason for ordering things, at least for safety.

    I have a Canon 100/2.8 macro and a 2x tele converter. Plus tubes and a bellows.

    The 2x teleconverter attached to the lens makes it a 200mm lens plus gives a 2:1 ratio in close up (instead of the 1:1 of the 'naked' lens.).

    It's a good way to achieve bigger magnification and not loose apperture coupling.

    The tubes can go after the teleconverter and increase magnification, however you need as much tubes as the lens' focal length to double the magnification. Hence the 200mm lens needs 200mm of tubing. A bellows comes in handy here.

    Another good thing of the teleconverter is that it doesn't reduce the working distance (~30cm) while tubes reduce that and also loose you infinity focus.
