I'm just getting into the world of macro. So here's my current macro setup, surprisingly not that heavy too!
Sorry for the horrible quality of the setup photos, what's shown: - Canon 400D. - Canon FD 70-210mm lens. - FD-EOS mount adapter with correctional glass. - Roughly 55mm of extension tubes. - Canon 430EX II speedlite.
Being as I already had the camera & the speedlite this was a bit of a fun experiment for an alternative to an expensive dedicated macro lens. I'm happy with the results.
