The AF201FG auto flash unit is designed for use with PENTAX lens-interchangeable digital cameras. This compact, portable unit has a maximum guide number of 20 at ISO 100/m, and features a dustproof, weather resistant construction to provide solid, dependable operation even under harsh outdoor conditions including rain and mist.

Compact body, with dependable dustproof, weather-resistant design for outdoor shooting - This auto flash unit has a compact, well-balanced body ideal for use with PENTAX K-series digital SLR cameras and the smaller, lighter Q-series lens-interchangeable models. Thanks to 18 seals applied in crucial parts of the body including the hotshoe, it features a highly dependable dustproof, weather-resistant construction. When paired with a dustproof, weather-resistant camera body and lens, it assures solid performance, even in harsh outdoor conditions such as rain and dust.

Bounce flash function up to a 135-degree tilt angle - The flash head can be adjusted vertically to 10 different angles (-10, 0, 30, 45, 60, 75, 90, 105, 120 and 135 degrees) for bounce flash operation. By bouncing the flash discharge off the ceiling or wall during indoor shooting, the user can soften the subject’s shadow to create more natural, true-to-life portraiture.

Simplified, dial-access operation - This flash unit features a simplified operating system that lets the user start flash photography instantly by turning the discharge mode dial, which double-functions as the ON/OFF switch. In addition to the OFF position, this dial provides a choice of four discharge modes: P-TTL auto flash with leading-curtain synchronization and P-TTL auto flash with trailing-curtain synchronization, in both of which the flash’s preliminary emission is detected by the camera’s light sensor to accurately control the main discharge level for proper exposure; and manual flash with full discharge and manual flash with 1/4-level discharge.

Other features - Built-in wide-angle panel that slides out to cover 20mm angle of view (in 35mm format)
