I would suggest you take your pick from either of these:
1. Canon 100mm f/2.8
2. Sigma 105mm macro
3. Tamron 90mm macro
I am not sure about Tamron but the other 2 perform very nice. Sharp clear contrasty macros. Excellent lenses both.
So you don't think its even worth looking at a 50mm macro? the 200 bucks LESS speaks to me a little on that subject
I don't really care about getting that close and scaring things. . .I don't take that many pics of bugs and whatnot:lol:
But I do definitely see the point of being farther away.
