    So, a coworker loaned me his set of extension tubes, & I was playing around with the 12mm tube mounted to a 20-35mm f/3.5-4.5. Results were interesting:

    Note the extremely shallow DOF (lens was less than 1" from the subject in all of these):

    Anyone else use these? I am thinking about picking up a 12mm tube.

    He let me borrow a 36mm one as well, but the DOF is way to shallow, and you have to have the subject virtually touching the lens.

    Any techniques I should try out while I still have the loaner tube?

    Thanks, also was testing out my new Sigma 500 DG Super flash at the same time - it works pretty well.

    Maybe you will finally be able to fill the frame with you microscopic penis.... :bigthumb:

    All kidding aside I have a 12mm too...I like shooting with the thrifty 50 and the 12mm. They seem to be a good match.

    Some were bounced, and some were using the diffuser panel (17mm setting). So far it is going great, I had a chance to use one for a weekend, and purchased one the very next week.

    I was somewhat skeptical about a Sigma vs. the 580ex, but 95% of the features for 1/2 the price is a fair trade IMHO.

    It was a kenko 12mm - the whole set (12mm, 20mm, 36mm) goes for ~$130. Canon offers them too, but for a hollow tube, it is not worth the extra $$.

    I would not suggest anything larger than a 12mm tube for lenses less than 50mm - you practically have to have the subject IN the lens to focus.

    Kenko is great...maintain all metering and autofocusing with my D70. (not that I use autofocus with extension tubes really)

    Haha, I 100% agree with you. For how much they cost, though, the cost is hardly justifiable.

    Have you seen a teleconverter before? It looks like a teleconverter without glass in the middle and they are a ton thinner. The Kenko ones have contacts but some of them do not. They just create separation between the lens and the body causing the min distance to focus to be decreased.

    dot. Subjects can be virtually touching the lens. Also, it not only decreases distance to focus, but DOF is extremely reduced as well. Think of extension tubes as a poor man's macro lens (when combined with any lens, that is).
