Key Features: Calumet GF400 Portable Flash System

The GF400 gives you excellent manual control of flash settings with compact form and ease of use. It features intuitive controls, a rotating head with 90° tilt capability, and removable reflector. This system has 7-stops of variable output from 1/128th to 1/1 power in 1/3-stop increments. Recycling time to full power is 4 seconds and the flash duration time is 1/300-1/10000 seconds. The GF400 features 5 different flash modes (Manual, S1 & S2 Slave Triggering, RPT Stroboscopic Flash, and Hi-speed Sync Triggering), and comes with an off-camera adapter base.

What makes this flash system exciting is the wide range of light control accessories available, including a 16-channel wireless trigger kit, an umbrella reflector, beauty dish with grid and snoot, to name just a few. Additionally, all Genesis light modifier accessories are compatible with the Quantum Qflash TRIO & 5dR flash units.

Other notable features of the GF400 include a large LCD display, simplified controls, a separate ON/OFF button, rotating head with vertical adjustments up to 90°, MF-Assist Beam (ideal for low-light or low-contrast conditions), Audio Ready function, and built-in overheating protection circuitry. Built-in PC sync and 3.5 mm sockets also provide flexible triggering options.

Each GF400 portable flash system includes a flash, flash tube, reflector with diffuser, power cable, 3 m (9.8 feet) 3.5 mm sync cord, mini-stand, an off-camera adapter base, protective bag, user manual, and is backed by a 1-year warranty.

The GF400 is designed to be used with Gensis PowerPort Duo 1000, and is compatible with a wide array of lighting accessories, including the Genesis Wireless Trigger Kit.
