Do you suggest using an extender/tele converter with a Macro lens such as Canon 100mm f2.8 macro lens?
Do you suggest using a teleconverter with a dedicated macro lens? I have tried out using a Kenko TC with canon macro lens - however I am not 100% satisfied with the "extra" magnification that I got on ...
Is there a reason only certain lenses can be fitted with an extender? I'd really love to be able to fit the extender to some of my cheaper lenses.
What are the negatives with using teleconverters?
