Ok so about to get a macro lens, either the tamron 90mm f2.8 or the tamron 60mm f2.0, so my question is which is going to give the best all round performance, interested in jewellery photography, bugs, but also as a general lens, portraits etc. For the bugs etc I assume the 90mm would be the best, but I thought the ability of the 60mm in general and low light conditions would be better, can you get close enough to bugs with a 60mm or do you really need a 90mm or higher, what does everyone think?
