I've gotten curious on macro photography lately, and I would like to get a starter lens. But I'm quite unsure of which one to choose. I'm gonna use it to shoot insects, flowers and close-ups of products. So I know I shouldn't buy a 60mm. But should I go for 85-90, 100-105 or 150-180? And as always ... which lense would you buy for macro? (Looking to spend 500-700$.) I got no experience in macro, so I'm looking for any advices regarding macro and lenses.
