The FL-36 Electronic-Flash is specifically designed for Digital with an accurate 1/8 step illumination control to provide the precision required by digital cameras, while minimizing illumination reduction. The built-in wide-angle diffuser panel will allow the flash to provide even illumination with wide angle lenses like the new Zuiko Digital 14mm-45mm zoom. The inclusion of a lockable bounce and swivel mechanism offers a variety of bounce photography options including left-right, as well as top-bottom in addition to a compact zoom Head to accommodate lenses from wide angle to telephoto.
