Sigma Electronic Flash Macro EM-140 DG NA-iTTL Ring Flash

About Me

I take photos. I travel. I do it for a living. Seven continents. Dozens of countries. Up mountains. Under water. And a bunch of places in between.

You can find my main site at havecamerawilltravel.com. Or check out what’s in my go-to travel photography kit.
