Quantum QD22WR Nikon and Fuji QTTL Adapter
QTTL adapters for popular digital and film cameras.
Two new QTTL adapter modules are now available: D12w-R for Nikon --- D13w-R for Canon. Currently only Nikon and Canon systems are capable of transmitting wireless TTL-Ratio commands directly to remote flash units. However, Qflash's wireless auto-fill feature gives other camera brands the ratio feature of wireless TTL.
Using the QTTL adapter for your camera, Qflash "Digitals" display and track the camera f/number and film speed set in the camera, allow for rear curtain sync, and provide infra-red auto focus assist.
QTTL adapters can offset Qflash output between -3 to +2 stops (in 1/3 steps) in relation to the f/number setting on the camera. Even if your camera doesn't support fill/flash ratio, the QTTL ratio setting tracks the camera aperture as it changes, providing automatic fill/flash ratio!
Digital and film cameras that employ "pre-flash" metering are also supported by Quantum's QTTL adapters.
