Description The Quantum Instruments D23wR QTTL Adapter for Canon provides pre-flash metering and E-TTL II (where supported) with the Canon Digital cameras. 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 the camera doesn't support fill/flash ratio, the QTTL ratio setting tracks the camera aperture as it changes, providing automatic fill/flash ratio. |
