Geekoto GTR 76 watt hot shoe flash (For Canon & Nikon)

Offering a powerful 76Ws output along with a distinct design, the Geekoto GTR Flash is an advanced light source with features that clearly reflect the current state of the industry. Compatible with Canon E-TTL / E-TTL II, this flexible on-camera light is distinguished by its round head, which provides soft, smooth light with gradual fall off that augments the flattering output. The head rotates 330 degrees, tilts -7 to 120°, and has a magnetic surface for lightning-fast attachment of Geekoto accessory light modifiers.

The GTR is powered by a removable 2600mAh lithium-ion battery that will give you up to 500 full-power flashes on a charge, so you don't miss any of the action. Speaking of speed, the GTR recycles to full power in just 2 seconds, fast enough to keep up with your subject. It also supports High Speed Sync up to 1/8000 sec, for managing bright backgrounds and shooting with wide apertures, and the GTR supports front and rear-curtain sync.

The GTR has an optical slave but it's also got a built-in 2.4 GHz receiver, which accepts wireless signals from Geekoto Commander System transmitters. In fact, you can control up to 3 wireless groups in a master/slave configuration whereby settings made on the V1 are duplicated on the slave flashes. Other convenience features include an AF assist lamp, a 3200K LED modeling lamp, and a 2.5mm port for cabled triggering.
