intova iss 2000 budget strobe - worth $130? in Lights, Strobes, and Lighting Technique Posted May 12, 2010 The fiber optic hookup will completely block the cameras flash, using it only as a trigger. You will eliminate the backscatter completely if you aim the strobe correctly. I had an Oly 770 in housing using an Epoque ds150 flash and it worked well. Only went to a DSLR rig after I gained lots of experience with the Oly and decided I would get into the hobby in a big($) way! Try out a cheap strobe, its way better than the built in flash.
