Made to withstand harsh conditions like fog and rain, the Pentax AF 540 FGZ II Auto Flash is built with 28 seals applied all throughout its parts making a weather-resistant construction. Even at a small and light design, it is still capable of having horizontal and vertical bounce in every shot.

Product Features in Detail

Dependable weather-resistant construction for demanding outdoor shooting
With 28 seals applied to crucial parts of the unit body including the hotshoe, these flash units feature highly dependable weather-resistant construction. By coupling one of them with a camera body and a lens that feature the same weather-resistant construction, the user can create a highly reliable weather-resistant digital imaging system that assures solid performance even in harsh outdoor conditions, such as in the rain or at locations subject to splashes and dust.

LED light convenient for movie and still-image recording
Both models incorporate a newly designed, high-intensity fixed-light LED light in their body. This white LED light comes in handy not only for close-distance movie recording, but also for still-image shooting requiring extended exposures. It also functions as a catch light in portraiture and an AF assist light in the dark.*
* The AF assist light function is available with 645D, K-r, K-5, K-30, K-5 II, K-5 II s, K-50 and K-500 camera bodies. The camera’s firmware must be updated to the latest version to support this function.

User-friendly function settings
The user can customize the flash operation by presetting as many as nine different flash functions to their preference, including the on/off of the catch-light function using the LED light and the choice of the flash discharge mode in still-image shooting.

Versatile flash control system
Both models provide a variety of flash discharge modes,** ranging from the advanced P-TTL auto flash mode in which the flash’s preliminary emission is detected by the camera’s light sensor to accurately control the main discharge level for proper exposure, to manual flash, high-shutter-speed synchronization and wireless P-TTL auto flash.
** Available flash discharge modes may vary depending on the camera body in use.

Other features
-Bounce flash function, adjustable to angles of -10 to 90 degrees vertically and up to 180 degrees horizontally 
-Power-zoom flash to cover angles of view from 24mm to 85mm lenses (in 35mm format) 
-Built-in wide-angle panel that slides out to cover 20mm angle of view (in 35mm format)
-Automatic setting of discharge angle in combination with a PENTAX lens-interchangeable digital camera body 
-Multi flash emission function available
-Shorter battery recharge time, in comparison to conventional models
