Compare Pentax AF-360 FGZ TTL Flash to Pentax AF540 FGZ TTL Flash

A professional flash for the Pentax family of SLR cameras, the AF-360 FGZ works with everything from the original 67 to todays 645N & MZ-S or MZ-SD cameras. Full manual control of flash output is possible, or use the TTL flash capabilities of the camera it is mounted on to achieve painless exposure with every aperture. The pop-up flash incorporated into many Pentax 35mm SLRs can be used to trigger the AF-360 FGZ wirelessly, and when combined with the MZ-S or MZ-SD this is done with TTL metering! Less

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. 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).
