The Qflash Model T2 is powered by the Quantum Turbo or Turbo Z Battery for Guide No. 160 (ISO 100) auto flash power. The Qflash Model X2 can be powered by the new Qpaq-X. It can also be powered by a Lumedyne or Norman pack, for up to 400 watt-seconds (GN 220, ISO 100 film) of auto-flash power.
Qflash uses parabolic reflectors for softer, cleaner light. The reflectors are removable for bare-bulb lighting. The flash head bounces and swivels. Flash control is either automatic, TTL (with optional adapters), manual, or stroboscopic. Automatic exposure control covers a nine stop range, adjustable every 1/3 stop, for a total of 25 automatic settings! Manual power can be adjusted from full to 1/64 power in 1/3 stop increments. Flash power can be precisely what you need. Stroboscopic mode can be adjusted for flash power, and number and frequency of bursts. Program lets you store up to 4 of your favorite settings (e.g. auto @ f8, f16 manual @ 1/4 power) and switch between them at a push of a button.
Qflashes can be ganged together to produce flexible lighting setups with thousands of watt-seconds of automatic or manual flash power. Qflash mounts on a camera bracket, tripod, or lightstand and weighs no more than a conventional flash.
Studio quality reflectors - To avoid harshness that can be produced by rectangular reflectors, Qflash uses a parabolic reflector. Angles of coverage : Normal position 55ø, Wideangle 70ø, with diffuser (included) 90ø, or remove the reflector for bare-bulb 360ø coverage.
