The Quantum Qflash Trio QF8C TTL Shoe Mount Flash combines several of Quantum's venerable Qflash system technologies into one complete dedicated shoe mount flash. Based on the popular Qflash, the Trio QF8 also includes a built-in FreeXwire TTL radio, for wireless TTL control, and is fully dedicated to the Nikon i-TTL flash system.
The Qflash uses parabolic reflectors for clean, even light spread, and the reflectors are removable for bare-bulb lighting. The flash can be used either on-camera on its own, on-camera as a master to other off-camera units, or off-camera with the use of a Pilot or FreeXWire module. The Ratio Control is highly adjustable between all the models in the set-up.
