Two Extension tubes, in the same 12mm and 25mm lengths as previously available, have been redesigned to accommodate the EF-S mount lenses and its extended rear elements. They're perfectly compatible with all previous EF and TS-E lenses, and will work with any EOS film or Digital SLR. Exposure compensation is often required with cameras other than the EOS-1 Series.

5.0 out of 5 stars It works March 15, 2006

By Frank Doherty

I bought the extension tube to allow me to get closer pictures of flowers. While it is a bit expensive, it does its job. I have been able to take several very creative close-ups that I couldn't do with just my 100mm Canon macro lens. I would certainly buy it again. I use it all the time.

5.0 out of 5 stars Works as Advertised April 28, 2006

By Brian Koch VINE™ VOICE

You can focus closer than without it, but you lose the ability to focus all the way to infinity. AF and TTL work just as good as without this between the lens and body. If you are interested in macro work you may want to look at the 60mm or 100mm macro lens before buying this since they allow 1:1 reproduction without any special attachments.

5.0 out of 5 stars Excellent piece of empty space October 18, 2005

By Kevin P. Barry

For a circle with a hole in it, this is well worth the money. Of course, you pay for the sturdiness of the piece, since poor build quality could definitely reduce the quality of your pictures. Don't be mislead by the description on Amazon, however. The site implies that this adds 25mm to your lens and that is it, whereas this will "macro-fy" your lenses. With this tube, my 28mm focuses from about 1-1.1" from the front of the lense, with a depth of field of a fraction of a mm at f/1.8. It's also strong enough to support my 200mm f/2.8L + 1.4x II, which is almost more than I can say for myself. My favorite use is in between my 85mm f/1.8 and 1.4x. I got stuck with a mark I, but I don't plan to use EF-S lenses anyway.
