So, I just bought this recently for my 50D, within the last month. I had wanted to get a lens that would take good pictures in low light, however I have found that my Tamron 17-50mm f/2.8 (with IS) fares just as well if not better for my purposes.


Bought through B&H for $439 and a B+W 62mm to 77mm step up UV filter for it for $78.95. Brand new, probably no more then 100 pictures taken with it. And a Tamron lens cap ($8)?


I'm potentially looking for the following lenses...


Canon EF 100mm 2.8 Macro (the latest version), Canon MP-E 65mm 2.8 1-5x macro, or Canon EF-S 17-55mm 2.8 IS USM.


I'm not entirely sure what I'm going to do, but I'm definately willing to entertain Trades/Offers...?
