I use a 17 -35 mm bought with my DSLR about 2 years ago and a 60 mm macro lens a very early version approx 8 years old for all my shots, both lens were designed to work with full frame film cameras, I cannot see any problems quality wise though scientific tests have shown lens designed for digital use are better but marginally. My feelings are if I was to purchase an outfit from scratch I would go with the appropriate digital version but the improvement in quality is not enough to make me change my present lens selection. I would really like the manufacturers make lens that gives the same focal lengths relative to 35 mm cameras i,e for a wide angle zoom of 17 - 35 not to turn into a 26 - 45 mm, please make us a true wide angle lens in the range of say 12 - 30 mm, then I would be ready to purchase a new lens.
