Complete your durable, rugged All Weather camera setup with the P-TTL capable Pentax AF-540FGZ II Flashgun which features 28 seals, including the hot shoe, that enable a reliable weather-resistant digital imaging system. This unit has a guide number of 54 m at ISO 100 and 85mm along with a 35mm equivalent zoom range of 24-85mm, though the auto zoom function is compatible with smaller format Q-series mirrorless cameras, APS-C DSLRs, and medium format 645-series digital cameras. Also, with the use of a built-in diffusion panel the coverage can be extended to 20mm. Another benefit of this flash is tilt from -10 to 90° and rotation 135° to the left and 180° to the right for complete bounce functionality.
The AF540FGZ II has wireless master and slave TTL capabilities with access to 4 channels. It utilizes an optical pulse to transmit information and trigger flash units up to 4 m away. Also, this unit can be set as a master, control, or slave unit and has access to a contrast control sync setting that enables the adjustment of the output of multiple flashes from a single unit.
An added feature for this flash is a constant LED light with 5 output settings for use during video, as an AF assist light, or as simply another light for your subject. Other settings include a multi-flash mode for stroboscopic photography as well as slow, high-speed, first and second curtain sync. Additionally, the AF540FGZ II runs on 4 AA batteries with a recycle time of 2.6-26.2 seconds and it comes with a case and stand.
