I Purchased the Speedlight 270 EXII and was in hopes to use it as a secondary flash. I took a trip to Thailand for three weeks and I found out to my surprise that I was using the 270 EXII as my primary flash during the daylight to brighten faces.
Small size, good flash coverage, cost, Tilt - Zoom capability, slave capable, Worked Very well on my G-16 and 18-300mm Tamron lens on my Canon 80D; Easy in / off capable
Battery life could be better, but not to bad; Carry an extra set of 2 if expecting extended shooting
