Ring Flash Adapter for Canon 580EXII with 1D,1Ds,1V

Ring Flash Adapter - designed for use with the Canon 580EXII flashgun with an EOS 1D, 1Ds or 1V camera body. The Ringflash Adapter is unique! It was developed by a professional photographer from the Czech Republic. It was designed to be as light and as portable as possible. There are no electronics, no flashtubes and no cumbersome cables! It uses a clever system of internal prisms, reflectors and light-shapers to distribute the light emitted from the flash unit evenly around the large diameter of the ringflash adapter. This creates the same lighting effect normally only available from ringflash units made by studio flash equipment manufacturers, which are expensive, heavy and tethered, i.e. have a cable from ringflash to power pack.
