The PL160 Dedicated Dual Flash (for Pentax) from Polaroid has full TTL dedication, plus a continuous LED light, making this a terrific light if you're shooting still photos and video, since you don't need to switch back and forth between flash and continuous light. The flash has a guide number of 148' (45 m) at 85mm/ISO 100, vari-power settings of 1/1, 1/2, 1/4, 1/8 and 1/16 and built-in "self-storing" diffuser and reflective panels.
The flash head tilts and swivels and features an auto zoom function that sets the flash zoom for the focal length of the lens (24-85 mm). Recycling time is between 0.5 and 9.0 seconds, depending on the power setting. A built-in optical slave function allows you to use this flash off-camera. An auto sleep mode means less charging time and more shooting time. The Dual Flash operates on 4x easy-to-find AA batteries.
