The Sony HVL-F32M External Flash is well-suited for use on mirrorless cameras as well as smaller DSLRs, or for those who are simply looking for a lightweight on-camera lighting solution. The flash balances power and size with a respectable guide number of 105′ at ISO 100 and 105mm as well as an auto zoom range of 24-105mm on full-frame cameras, expandable to 15mm with the built-in wide-angle panel. Also, unit can tilt upward 90 as well as rotate 180 right and 90 left for bouncing light in horizontal and vertical shooting positions.
