I am really pleased with this flashgun. As a novice I find it hard to justify spending the kind of money needed to buy a Canon flash gun. However, the Sunpak meets all my needs.
It is great on camera and takes full advantage of the ETTL producing fantastic results. The tilt and swivel flash head allows you to bounce the flash giving you access to a wider range of photo setups as well as balancing the background in dark conditions. My remote triggers do not support ETTL but Sunpak has preformed well off camera in manual mode.
The only downside to this flashgun is the manual which is a very basic.
