Canon F-1 Digital Camera User Manual


 
Dioptric Adjustment Lenses
The Rubber Eyepiece Ring — the glassless ring covered
with rubber — is attached to the viewfinder. Camera's
standard diopter is —1.2, while ten other kind of screw-
in type dioptric adjustment lenses are interchangeable.
The diopters of these lenses are adjusted solely for use
with the F-1. Thus, the diopters of the lenses are not
"true" to their markings when the lenses are used by
themselves, but are "true" to their marking when the
lenses are taken in conjunction with the camera.
Dioptric adjustment lenses can also be used when a
Magnifier R is attached to the viewfinder eyepiece.
Dioptric adjustment lenses should be removed when
the Angle Finders A2 and B are attached, which are
adjustable.
Angle Finder A2 and B
The Angle Finders A2 and B can be attached to the
eyepiece for copying, photomacrography, and photo-
micrography.
Magnifier R
The Magnifier R can be attached to the eyepiece which
magnifies the rangefinder section for accurate focusing.
Because it can be flipped up and locked, the entire
field-of-view can be easily viewed after focusing.
