With a maximum guide number of 54 (at ISO100/m), this high-capacity, clip-on auto flash features a dustproof, weather-resistant structure to deliver dependable performance even under demanding outdoor conditions, such as at dusty locations and in the rain. Since it features a powerful white-LED flash head and an AF-assist light for shooting in the dark, it can be used not only for close-range movie recording, but also for still-image shooting with extended exposures. It provides nine custom functions to personalize its operation, including on/off switching of the LED light when used as a catch light, and setting of the LED light’s discharge mode in still-image shooting.

This auto flash features a dustproof, weather-resistant structure identical to that of the camera body, with 28 sealing parts applied across the unit, including the hot shoe. Its power switch, control dials and buttons, and battery compartment are all completely sealed to provide an airtight structure. It even has a tightening knob to eliminate gaps between its hot shoe and the camera’s contacts. A light twist of this knob assures solid connection of the electrical contacts, while preventing the intrusion of foreign substances.
