I use the old 100 f2.8 macro and it is a great lens as a dedicated macro lens. If you want to use it as a non-macro you might want to get the newer version with USM as the auto focus on the older version is relatively slow. However, for macro work I manually focus. Don't get me wrong, if you are shooting static 'non-macro' subjects the auto focus is just fine and I have no problem with its accuracy, it is just slower than the USM. The lens is extremely sharp. I should also mention that it does not focus internally, so the length changes, though the front element does not rotate so you can still use a polarizer.
I am quite pleased with the results. Most, if not all of the pictures in the flower gallery on my web site were made with this lens. You're welcome to take a look, though I don't think you can critically assess sharpness or color contrast on a scanned JPEG web photo. http://www.grillphotographic.com In short, I have been very pleased with this lens. I have not used ring flash. Howard > I'm thinking of buying a 100mm f/2.8 Macro. Can anyone point me to some > web sites that might show works done with this lens?
