Extension Tubes and Ring Flash?

Monday, January 30th, 2012

A reader asks on my Comparing macro lenses to extension tubes page whether or not hot-shoe or ring flash will work with extension tubes, or whether the working distance is too close.

Answer #1: I don’t know. Answer #2: Let’s find out.

I set up a tripod, put a 6 mm extension tube on a 16 mm lens, and asked Uiharu to model for me. The crinkled paper was intended to give a bit of light bounce from the room lights, but I ended up shining a flashlight into the paper to push up the brightness.
