I have an Olympus 7070 camera with the Olympus housing, I have used it for several years and have gotten good results, I am in the market to make the next jump forward to a SLR camera and housing. After comparing the options, the Olympus E-520 with the new Olympus PT-E05 Housing (when available) looks like it might fill my requirements, I like the feature of fiberoptic firing of the strobe vs electrical connections (I already have an Ion strobe D2000 which utilizes this), and the system price is lower than other systems with aluminum housing. I would like to get feed back from others.
