If the lens is 3rd-cam or ROM the inside diameter of the tube's lens-side flange needs to be milled a tiny bit to accommodate the lens' R-only flange. To use the modified tube, set the lens' aperture ring at the minimum aperture and use the aperture ring on the tube instead. The fully-modified tube is what I call the Universal Extension Tube-R (UET-R) because it's compatible with the greatest number of lenses and bodies. It's technically friday so I can mention that I modify and sell the tubes as the UET-R. Doug Herr Sacramento http://www.wildlightphoto.com
