The Sunpak PF20XD Wireless Flashgun is a very compact & lightweight unit ideal to be used with digital compact cameras as well as DSLRs. It can be attached directly to the hotshoe or on a bracket & the built in slave sensor will detect the firing of another flash source (eg the built in flash on the camera) while the auto sensor automatically adjusts the output for perfect results. There is also full manual control over the power output in five steps via a dial on the back of the unit. Powered by two AAA batteries the recycling time to full power is around 9 seconds & a built in wide angle panel extends coverage to a 20mm lens.
