Note: The Rayflash Ringflash adaptor can be used with most of the Canon & Nikon lenses but not all the lenses. Some large zoom lenses may not be able to fit in the Ringflash adaptor.
Exposure control: when using Canon or Nikon cameras (or their derivatives) all TTL functions are operational as usual, as well as manual mode. In MANUAL control of the exposure is by use of a light meter or through test-shots on a digital camera.
Light output: The Ringflash Adapter is very efficient and the loss of light is surprisingly low! There is a difference in light efficiency between the SIRC and the RAN/RAC models, the latter being more efficient.
