This PENTAX digital camera flash has a weather-resistant construction, LED light, and shoots at the guide number ranging from ISO 36 to 100. With its rugged design, it can be used even under harsh weather conditions, in rain or fog, but also in places where it may be splashed with water or in a dusty environment. The body has built-in LED light, which you will no doubt appreciate when shooting at short distances (such as macro) and for the better lighting it provides for video clips.
The user can customise flash operations by pre-setting nine different functions. It also offers a range of launch modes, including the advanced P-TTL auto flash mode, which features a pre-flash that is detected by the camera's sensor to accurately align the main flash. This ensures the correct exposure. The flash also includes high-speed sync and wireless P-TTL auto flash.
