Recently, I have bought those two bodies. I have had a few EF lenses. 17-40, 4L 50, 1.8, version 1 with metal built 85, 1.8 100, 2.8 macro... version one 135, 2.8 sf 200, 2.8L version 70-200, 4L 1.4 and 2.0 extension What do you think I should get next? Since 24-70, 2.8L doesn't have good reviews, and i don't know where to get 28-70, 2.8L. What can I do with this range? I think I eventually should have 70-200, 2.8L IS ii (what's the difference between i and ii?) I enjoy nature, macro and getting into event, portrait.
