I’m starting to get into macro photography and don’t want to spend too much as I go through the learning process. I have a 7D, my budget is $400 +/- and looking for something compact. I’ve narrowed it down to three lenses; Canon 50mm f/2.5, Sigma 50mm f/2.8 EX DG and Canon EF-S 60mm f/2.8 in order based on cost. Is there another lens I have not considered? Which one of the three lenses above would you recommend?
Thanks to all the suggestions. I should be receiving a brand new Canon EF-S 60mm f/2.8 macro in the mail within five days. I took advantage of the Canon $40 instead rebate for this lens and an online coupon to get the price down to a few dollars above $400.
