I don't think the 510 will fire the flash remotely. I've been trying to justify spending the $200 on the FL36R, would LOVE the FL50R. I have this job for sure, plus one other, as well as two more possibles. All are senior pictures. I have done two seniors before (one was my daughter, who was not too happy to have me do them. I told her I'd pay the money if she wasn't happy with what I did. Fortunately for me, she was happy!)
I have wondered if I made a mistake getting the Olympus. As much as a I really do like the camera, and preferred the feel to the Nikon and Cannon, but the lenses are SO expensive for the Olympus.
