Pentax AF540FGZ
Pentax AF540FGZ auto-flash unit introduced
Pentax Corporation have announced the marketing of the Pentax AF540FGZ auto flash unit. This unit features a large guide number of 54 (at ISO 100) and provides a variety of advanced flash applications, including advanced P-TTL auto flash, high-speed synchronisation and wireless P-TTL auto flash (when mounted on a Pentax SLR camera).

When mounted on a Pentax auto-focus 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. (Please note this automatic function may not be available for certain combinations of a camera body and lens.)

The AF540FGZ auto-flash unit also features a newly provided 'Digital' position on the focal-length conversion scale of the zoom head which can accommodate digital SLRs, Bounce Flash function with adjustable angles of -10 to 90 degrees vertically and up to 180 degrees horizontally, and Power-zoom flash head to cover angles of view for 24mm to 85mm lenses (in 35mm format).

The flash unit also incorporates a built-in wide angle panel which slides out to cover 20mm angle of view (in 35mm format) and a built-in catch-light panel which is particularly useful and effective for portrait photography.

The AF540FGZ auto-flash unit is compatible with a range of batteries, and is able to run on either 4x AA alkaline batteries, 4x AA lithium batteries or 4x AA Ni-MH batteries. An optional TR Power Pack II is also available for an external power supply to the unit. To maximise battery life an auto power-off function is included (this can be cancelled by the user).

The flash unit, which has dimensions of 142mm x 76mm x 107mm and weighs 380g (without batteries) also features test discharge, modelling light, spotbeam projector and red-eye reduction.
