comment:I was lucky to pick up a minty copy on fleabay for significantly less than I thought I was going to have to pay - lucky me! I really like this lens, although realistically it's only viable handheld in good light. It loves a good tripod, and I have achieved some excellent moon shots with it.
In side-by-side comparisons with the 70-300G, it gives a little away in sharpness, colour and contrast, but renders excellent detail at max focal length stopped down a couple and is not embarrassed by the more expensive G. CA is not an issue. Without a good contrast to focus on, it will hunt but once you understand that this is a slow, dark lens and adjust your technique accordingly, you can obtain some surprisingly good results for a pre-digital coatings lens (mine is stamped 1995). All in all, I'm very happy with mine. I'd love a 70-400 G, but until I can afford one, this will do just fine.
