Darn, hit the send key too quickly. The rep is full of it. Most of the reps you run across know very little and pretend to know much more. Basically imbeciles that can talk well. The loose front element should not be. The lens is a Planar type and there is no such thing as a loose element in that design. Even the Hassy floating element system in several lenses was not "loose." Sent it in to Canon. As to your test, would love to see the results. Personally, I never thought the Canon Macro was great. I opted for the Tamron 90mm (sharper), the Sigma 105mm (as sharp as the Tamron but longer but has lousy bokeh) and now the Sigma 70mm which is the best I have had. I would still be in terested in how you mounted the Nikon on a Canon EOS. But if it works for you, use it. I would love to find a Kiron 105mm F2.8 in any mount that can fit the EOS. As I said that was the sharpest macro I've ever used. And yes, I have used the Nikon 105mm. Incidentally, yours is better than the new VR version.

To Peter and the group, Legends aside, I recently did a head-to-head test on my 1Ds between the new Canon 100mm Macro and my 35 year-old Nikon 105mm Macro.The older lens was sharper with less vignetting. But the loose front element on my Canon 50mm f1.4 bothers me. After using it a few times, I called and complained to a tech rep saying that I could loose image registration due to movement in sequential frames when inserting a gel filter in my bellows lens shade. The tech rep said I should not use a heavy lens shade (buy a Canon one instead!). Furthermore, he explained that the "loose front element" was part of the focusing system of that lens. I pointed out that no other lens I owned, old, new or crappy had so much wobble. Well, other Canon lenses have internal focusing, but that's the way the 50mms are made, he said. End of discussion.
