Leaf shutter lenses are equipped with an internal shutter. When set on X, leaf shutter
lenses charge quickly and are capable of high shutter speeds (1/800 sec.) with flash
synchronization during daytime shooting. By merely pressing the shutter button, the
leaf shutter will automatically charge, allowing for rapid photography.
When the leaf shutter lens is attached, the letters “ ” will appear in the main LCD
display. (The leaf shutter icon will also appear).
When using settings “P” (Program AE), “Av” (Aperture priority AE) or “Tv” (shutter
priority AE), it is possible to change to focal plane shutter photography.
