I run the DAF-14 on a Canon EF 100mm / 1: 2.8 Macro USM lens with 58mm filter thread to replace the tested compared to me personally but to expensive original ring flash to the fullest satisfaction. For this price range gripes do for me to date even after hundreds MacroPix NO on ;-) While the flash Konstanz may certainly be better in the original series, but for almost a tenth of the price I'll take it like in buying.
