It is common knowledge that to take decent flash pictures, one needs to get the flash as far away from the lens as possible. I had a great external flash for my C-2100, a Promaster 5750DX. One of the best features of this flash is it has through-the-lens (TTL) capabilities for many different cameras, it just needs a specific module for the individual camera. The C-2100 required a PC-sync cable since it didn’t have a hot shoe, so the module for it has the cable. However, my nice new E-500 only has the hot shoe, and I finally got the module for it!! I’m so excited.
