hey guys, since right now i was too late to raise money for the supertele, i decided to go to the other side my setup is currently lacking,----macro. for macro, i have tried the 50mm and 90-100mm range before. so far, 50mm is kind of quite useless to me as its distance to achieve 1:1 is like so darn close. right now, i know alot of pp going to recommend the tamron 90mm, but i just need to know whether it is worthwhile to get the 180mm macro. i haven't used 180mm macro before so i can't really relate my experiences with it. do any of you think that 180mm would be a better choice as compared to the 90mm? thanks!
