Interesting. This is one of those lenses I love to rag on even though I used mine a lot. Optically I thought it pretty decent, and the 35-105 range was nice for film, an ideal walking about lens....except that I always thought it an ergonomic mess. The push pull zoom was, like so many, loose, and because it's nowhere near parfocal, one has to hold on tight to keep it from creeping out of focus. The pseudo-macro setting is clumsy too, and because of the zoom creep it's essentially unusable on a tripod unless you carry a roll of tape. As I think I've mentioned before here, I bought mine at the same time as I got the 80-200 F4 AIS, and was always a little amused that that wonderfully sharp, constant-aperture, non-creeping, close focusing, parfocal zoom could have been made by the same company.
e.t.a...on the other hand, the article cited suggests that the lens is far better in the center 70 percent or so than at the edges, so perhaps I'll have to try it on DX.
