I haven't done any macro photography yet, but work of champions here (Lil Jud comes to mind) amazes me every time I see the pics clicked by them, and am looking for a future Macro lens recommendation. I understand that you need to have some tele length available so that you can stay away from the creatures/bugs as well as use flash if needed. I see myself clicking lots of flowers etc as well, probably more than bugs.. but I am guessing buying a lens with more tele is better than shorter tele length... but I might be wrong. What else is important thing for macro lens ? (I have D90) what about the ratio... ? Also are macro lenses strictly for macro (extreme closeup is what I think macro is supposed to mean... micro to be correct?) or can they or should they be used for general pictures etc ? I hear good things about Tamron 90mm (but just recently returned Tamron 17- 50 as it won't focus right) and it's priced within my range too. Are there any other recommendations for a beginner macro experience ?
