im currently looking for a nice macro lens for my canon eos A2 because i really enjoy macro photography. the ones im looking at are: Tamron SP AF 90mm f/2.8 Di macro $359.99 plus shipping and tax (after 40 mail in rebate) Sigma AF 105 f/2.8 EX DG macro $339.99 plus shipping and tax Canon 100mm f/2.8 macro USM $449.99 plus shipping and maybe tax... Trying to spend as little as i can, since im also trying to save up for a rebel xt or xti (depends how much i have when i decide to buy one) as much as i love film, digital would be more convenient for me. The rebel is gonna be a while, but im hoping to get the macro lens soon. thanks for all help and suggestions!
