FINDER GROUP AND UNITS
The viewfinder is one of the most im-
portant features of a single lens reflex
camera. Since every photographic sub-
ject is turned into a visual image by
means of the finder, a finder that is dark
or difficult to look through is an ob-
stacle to good photography. However
enriched an SLR camera is with a wide
range of interchangeable lenses, the
SLR cannot be expected to fulfill its
essential function without the provision
for changing of focusing screens. The
OM-1 is provided with a viewfinder
that offers a far brighter, larger image
than conventional 35mm SLR cameras.
The Finder Group supplements this
basic advantage with a comprehensive
set of 13 focusing screens for a wide
variety of applications from photo-
micrography to astrophotography.
Unless the most suitable focusing screen
for given photographic purpose is avail-
able, the potentialities of a system
camera cannot be utilized. For fast,
accurate focusing, the OM System
Finder Group offers the unique Vari-
magni Finder with a magnification
selector, the Eyecup 1 that accepts a
variety of Dioptric Correction Lenses,
Eyecoupler, etc.
Varimagni Finder
This unique and exclusive unit for the
OM System combines the two functions
of angle finder and magnifier, incorpo-
rating 9 lens elements and a reflector. It
fits over the camera's eyepiece, and can
be adjusted for individual eyesight. Its
eyepiece tube is rotatable through 360°,
for use in low level and 90° angled shots.
The two-stage, one-touch switching
system offers both a 1.2x magnification
image covering the whole screen, and a
2.5x enlargement of the central portion
for critical focusing. For photomicro-
graphic use, insert the Eyecoupler
between the camera and Varimagni
Finder.
Eyecup 1
Attached by sliding over the OM Body
eyepiece. With its attached rubber hood
it prevents stray light from entering
through the eyepiece, an essential
requirement in light measuring. The Eye-
cup 1 is provided with a slot to accept
a dioptric correction lens.
Eyecoupler
Connects the Varimagni Finder to the
OM Body for photomicrography. It also
ensures full coverage of the bright
viewfinder field for use of the Eyecup 1
in conjunction with the Motor Drive
250 Film Back 1.
