Handheld Macro BG control basics

[Jonathan Michael Ashton]

would this help for for macro???

Canon MR-24EX Macro Ring Lite



with a macro 100 2.8 lens???

I a not too sure if that ring light is for non digital cameras, and the digital cameras now use a twin flash unit. If you already have a conventional gun I would recommend using that with a diffuser, it gives great natural looking results.
