The Quantum Instruments Qflash TRIO QF8 Flash for Canon and Turbo SC Power Pack Kit
contains a TTL-dedicated shoe-mounted flash and a matching portable power pack.
The TRIO stems from the original Qflash system and incorporates many of its technologies into an efficient shoe-mounted flash. Featuring a built-in FreeXwire TTL radio, this flash is capable of acting as a multi-flash group commander dedicated to the Canon TTL system. 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 SC Power Pack is also included to provide more than 400 full-power flashes per charge with an average recycle time of 1.5 seconds. This compact power source measures just 5.14 x 3.6 x 1.3" and weighs less than 1lb for convenient portability.
