The Pentax AF540FGZ II Flash is an on-camera flash that is compatible with Pentax DSLR cameras. The AF540FGZ II has a guide number of 177' at ISO 100 and an effective range of 2.6 to 26.2'. Additionally, it features an all weather construction with 28 seals that pairs with Pentax weather-resistant cameras for safe operation in all conditions.

This flash features wireless functionality with access to 4 channels. It utilizes an optical pulse to transmit information and for triggering additional flash units up to 13.1' away. The AF540FGZ II can be set as a master, control, or slave unit and is able to use both manual and P-TTL while in wireless mode.

Full manual and automatic P-TTL controls are available on this flash. Full manual mode features nine steps of adjustment from full 1/1 power to 1/256 power. While in P-TTL mode, flash output compensation can be applied from -4 to +2 stops in either 1/3 or 1/2-step increments.

Additional creative control modes allow for specific effects to be created using the flash. For example, high-speed sync allows you to use faster shutter speeds than the camera's rated flash sync speed. Also, the LED light can be used as a continuous light source for video and long exposures.

Included with the AF540FGZ II are the O-AC141 Case for storage and a stand for setting up the flash off-camera.

Creative control modes include first-curtain sync, second-curtain sync, high-speed sync, and contrast control

      Well constructed, smaller than old 540, more efficient and fast... I was waiting long time for Pentax introducing new devices. Finally, the day is in!
