Cactus is launching a compact, battery-powered strobe that offers TTL metering for eight different camera brands and a robust battery life of 520 full-powered shots per charge.
The 250 W/s RQ250 features a removable round frosted diffusion disc that can be pulled off to reveal a bare bulb. It features a proprietary Cactus bayonet and will mount to a Cactus softbox, though a Bowens mount adapter will also be sold as an optional accessory for using a wide range of light modifiers.
The mount has built-in magnets so you can pop on a series of magnetized gels and grids to modify the light. Cactus will offer a gel holder, honeycomb grid, snoot, barn doors and a dome diffuser that will work with the magnetic mounting system.
Using the V6 II transmitter, you’ll enjoy TTL metering for Canon, Nikon, Pentax, Olympus, Panasonic, Fujifilm and Sigma cameras. The V6 IIs transmitter will be required for Sony models. The flash has a built-in 2.4GHz radio receiver and supports 16 channels in four groups.
Recycle times clock in at 1.1 seconds at full power. Power is adjustable across a 10 stop range (or 8 in HSS) in 1, 1/2, 1/3 and 1/10EV steps. Flash durations (t0.5) can reach 1/37,000 sec. at lowest power. There’s also a 20W modeling light.
