  1. Dependable weather-resistant construction for demanding outdoor shooting
    With 28 seals applied to crucial parts of the body, including the hotshoe, the new AF540FGZ II and AF360FGZ II feature highly dependable weather-resistant All Weather (AW) construction. When coupled with a PENTAX weather-sealed DSLR camera body and lens, 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.

This white LED light comes in handy not only for close-distance movie recording, but also for still-image shooting requiring extended exposures.

  4. 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.
