Gift was perfect!!

A lot of functionality in a camera mounted flash
“I’ve owned this unit since March 07 and have used it sparingly. The performance to date is as advertised and impressive for a camera mounted flash unit. However, the mounting arrangement incorporates a metal spring loaded ‘lock pin’ which fits into a receptor hole in the camera hot-shoe.” – By Donald G. Fraser

Pentax AF540FGZ
“Great features and the remote feature is awesome. The smart zoom functions quite well and auto recognizes the use of internal defusers. All in all, a great flash.” – By JC

Great Flash!
“Very capable flash. Great value when compared with after market units for Pentax DSLR’s. Features like auto zoom that matches the lens focal length, wireless remote operation and P-TTL auto flash with trailing curtain sync make this flash a bargain at twice the price. “ – By David Quesnette

Works like a charm
“For an amateur like myself, this has been a blessing. Having never worked with an off camera flash or a camera mounted auxillary flash, the guide along with some online sources has really helped me to let this flash enlighten my gallery. “ – By Michael Morgan

AF540FGZ Flash by Pentax
“The flash is everything I expected and more. The wireless mode works flawlessly in typical Pentax fashion. It’s quite easy to use, easier than I expected it to be. Very powerful and the P-TTL system works very well. I’d recommend this flash to all Pentax camera owners whose camera uses the P-TTL exposure control system. “ – By J. Hausmann

Advanced auto flash functions
The AF540FGZ features a variety of flash functions, including advanced P-TTL auto flash in which a pre-emission from its spotbeam projector is detected by the camera’s light sensor to accurately control the main discharge level needed for proper illumination of the subject.

Auto discharge-angle adjustment
When mounted on a Pentax autofocus SLR (after the Z-10 and including digital-format models) equipped with an FA-, FA J-, DFA- or DA- series lens, the AF540FGZ automatically adjusts its angle of discharge to the lens’ focal length (automatic function may not be available for certain combinations of a camera body and a lens).
