Pentax AF 540 FGZ II Flashgun
The AF540FGZ II is an auto flash unit for Pentax lens-interchangeable digital cameras, featuring weather-resistant construction and LED light for movie and still-image recording. It has a maximum guide number of 54 at ISO 100/m. This unit is designed to provide solid, dependable operation even under harsh outdoor conditions including rain and fog.
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 for movie and still-image recording
The AF540FGZ II incorporates 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.
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
This unit 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 synchronization and wireless P-TTL auto flash.
** Available flash discharge modes may vary depending on the camera body in use.
