The AE Prism Finder FE401
The Mamiya AE (Automatic Exposure) Prism Finder
FE401 pentaprism guarantees a true, upright image
and features built-in electronic shutter control which,
ensures aperture-priority, TTL automatic exposure
metering while in the A or AEL mode.
< 3-Way Metering System>
The FE401 comes with three metering modes: average
metering (AV), spot metering (SP), and AV-SP metering
capable of automatically selecting AV or SP according
to subject conditions.
The LED display in the viewfinder indicates correct
exposure
If you forget to extract the Dark Slide when the finder is
being used with the 645 PRO, an LED will flash a
warning.
The Power Drive Grip WG401
The Power Drive Grip WG401 is integral with the
winder and hand grip, enabling quick and continuous
exposures to be taken: frames can be advanced (about
2 frames/sec.).
Usable with any of three recently developed leaf shut-
ter lenses, it can be connected with the lens and winder
with the Grip Connecter PL401, thus automatically
interlocking it with the lens.
