Hi Boris, I have a Sigma 70-300mm f4.0-5.6 Apo Macro Super and find it really useful. I've used it regularly now for about a year and have no complaints. As a macro it works better than I expected and if you want to chase butterflies around the garden it's ideal; giving half life size images at the Macro 300mm setting. If you do a search on the web you'll find a few informative reviews. Its a 35mm lens of course. I don't know anything about the DG version. The MTF looks good for 35mm and looks *really great* for the smaller sensor of the *ist D. There are several other versions of this lens that don't perform nearly as well. There is no chromatic aberration to speak of -- even in the corners. I haven't used it on a film camera, but would expect to find them. Maybe some of our other members have the same lens? The Apo Macro Super has a gold band around the front and is on page 8 of the Sigma lens catalogue.
