 Hi Photographer friends,

AF540FGZ II and AF360FGZ II Flash Units

The AF540FGZ II and the AF360FGZ II professional flash units update the Pentax models presently available and have added not only power and design durability, but features to enhance video recording as well. Compatible with Pentax SLR, DSLR, and mirrorless cameras that have a hot-shoe mount, they are powerful and versatile. Their new all-weather construction pairs well with the Pentax WR DSLR cameras. High maximum guide numbers (177.2’ for the AF540 and 118.1’ for the AF360, both at ISO 100) indicate more power than their predecessors; their effective flash ranges run to 26.2’ for the AF540 and 17.7’ for the AF360. They are both auto zoom enabled when shooting with a compatible autofocus camera-and-lens combination.

Pre-flash in P-TTL mode provides more accurate strobe shooting. High-speed, on-camera, and wireless flash is available in P-TTL. Both models offer a constant light source for videos or long-exposure still photography and an improved LCD shows the effective flash range. A simple dial is available to control flash exposure compensation. The AF540FGZ II and the AF360FGZ II can also act as both commander and slave via their optical pulse transmission wireless shooting function. With up to four channels available, the wireless function enables effective, coordinated off-camera flash setups for creative lighting control.
