Not sure if I should post this here or the consumer's corner forum.
Anyway, I have a Sigma 80-200mm f2.8. Have been adding a Canon 500D for Macro. Wonder what is the next piece of equipment I should get....a 2xTC or an Extention Tube. The performance of my old Sigma 90mm Macro is not too consistent.
Any advice from the Macro lover out there?
