Contrary to what I read in other ratings I found the Kenko extension tubes well made and solid. There was no lens drooping that I could detect (even with a Sigma 70-200mm f/2.8, but I did have to support the lens for balance) and the product worked as advertised.One disadvantage is the focal length as viewed from the camera wrong, because the camera does not know that the extension tubes are attached to appear, the tubes transparent to the camera, but thats no big deal, when recording macros, as you usually have time to check the exposure, and adjustments for another shot..
