Flash System[For 645NII]
Dedicated Auto Flashes
AF540FGZ Dedicated Auto Flash (case included) Discontinued
This high-performance clip-on-type dedicated auto flash offers the maximum guide number of 50 (at ISO 100/m) and a wide 24mm angle of discharge. It also features an auto zoom mechanism to couple its angle of discharge with the selected lens focal length, and an adjustable head that swings vertically and horizontally for bounce-flash applications. In addition, it simplifies such complicated applications as trailing-shutter-curtain sync flash, multiple flash and slave flash, while incorporating an AF spotbeam projector to assist the camera's AF system.
