The Quantum Instruments Qflash TRIO Basic QF8 Flash for Canon and Turbo 3 Power Pack Kit
contains a TTL-dedicated shoe-mounted flash and a matching portable power pack.
The TRIO Basic stems from the original Qflash system and incorporates many of its technologies into an efficient shoe-mounted flash. This flash is compatible with Canon's TTL system and supports AF assist, high speed sync, and other camera-specific flash settings. The bare bulb design and ability to accept parabolic reflectors and other light modifiers provide studio-quality lighting from the convenience of an on-camera flash.
A Turbo 3 Power Pack is also included to provide more than 1000 full-power flashes per charge with an average recycle time of just 1 second. This portable power source can also be used to provide additional battery power to your digital camera while powering the TRIO Basic flash at the same time.
