Dependable weather-resistant construction for demanding outdoor shooting
With 28 seals applied to crucial parts of the unit body including the hotshoe, the Pentax AF 540 FGZ II Flash features a highly dependable weather-resistant construction. By coupling the flash with a camera body and a lens that feature the same weather-resistant construction, you 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
The Pentax AF 540 FGZ II Flash incorporates a newly designed, high-intensity fixed-light LED light in its 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 with selected camera bodies.
User-friendly function settings
You can customise the flash operation by pre-setting as many as nine different flash functions to your 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
The Pentax AF 540 FGZ II Flash provides 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 synchronisation and wireless P-TTL auto flash.
