poetic photo by k. lynne Posted January 29, 2008 Share Posted January 29, 2008 I just bought my first dslr, and I am painfully learning how to use it, the store manager gave me the Promaster 5750DX Flash unit to use with my evolt. I have never used a flash like this, so help me out. Yesterday when i used it, sometimes it would fire, sometimes it wouldnt. Sometimes only one flash would fire and not the other. Am I doing something wrong? And can someone suggest a website that may teach me how to use these kind of flashes? And are these even compatible?

paul_miller10 Posted January 29, 2008 Share Posted January 29, 2008 I use the Promaster 5750 on my E-10 and E-500s. The issue yopu are probably dealing with is due to the OM module mounted on the flash. The early version of the module was originally designed to work with the E-10 and E-20, but I never could get it to work with E-Volts or the E-1. Last year I bought the newer module and it works very well with my E-500s. They look the same and have the same I.D., so I put tape labels on the bottom of the modules so i know which is which. Go back to the store and try other OM modules from Promaster. Link to comment Share on other sites More sharing options...
