Reviews : Evaluation: Conclusion: Very capable flash Review: I was torn between the DG ST and the Super, but in reality I wouldn't use the extra features at all, or very rarely. This is a nicely built unit, the swivel, and zoom lock so things stay put. The Pentax 360 is stouter, but over twice the money. This recognizes all the features and functions of the camera. The flash has proven to work well with my ist* DL. I have only had it a few months, and haven't had a chance to use it very often as I am a picture taker, not a photographer. If you can live without a LCD readout, or the wireless slave features, this should do well for you. If you are into serious photography, and need all the bells and whistles, you should probably look elsewhere. I can't speak to longevity, and I doubt this would survive a serious fall, but with its features, power, and built in diffuser, zoom, and swivel head, I'm satisfied. Dan More Evaluations
