O
The
Rolleitneter
The Rolleimeter
is
a
coupled
optical
rangefinder
which transforms
the direct viewfinder of
the Rolleiflex
Automat
(1950
and
later models)
and Automat2.S
into a focusing frame finder,
permitting
simultaneous
viewing and
focusing at eye level. This is specially useful
when taking
sports
shots-rapid
action is
easier
to
follow
in the frame finder than on
the screen-or
when working in
poor
light where
the screen
irnage
is
difficult to observe
clearly.
The
Rolleimeter
is
attached
by means of a simple
clamping
screw
to
the name
plate
of the
camera. Focusing the camera causes
the moving
front
panel
to actuate a
lever
which,
in turn, transmits the
motion
to
the rangefinder. A vertical
glass plate
with a semi-silvered
spot
in
the
middle,
is located in the centre of the frame
finder at 45" to the
plane
of the front frame.
This
provides
the
means for viewing the two clearly
distinguishable
focusing images.
On
turning the focusing
knob
of the
camera the
two
images fuse into one when
the camera
is
correctly
focused.
Before
using
the Rolleimeter for the first
time,
a simple
infinity
(oo)
adjustment of the
instrument
to coincide with the
camera is required.
A
protective
cap
is
provided
over the adjustment
screw to secure the
setting
permanently.
A special model Rolleimeter C
is
available
for
use with the
Rolleiflex
2.8
series.
The
Rolleimeter is
supplied
in a leather case, which
may
be fastened
to the strap of the ever-ready
camera case. It is not usable
for the
Rolleiflex models E, F, T,
Magic
or 4x4.
O
The Extension Focusing Knob
The Rolleiflex Automats since 1954 and the
later models have a large
focusing
knob, designed for focusing under
adverse
conditions, e.g.
when wearing
gloves,
or when the camera
is in its case. For the
pre-
1954 Automats an extension focusing
knob is
available.
The extension
knob
is bigger than the
original
focusing
knob,
and easier to
grip.
To fit
the extension
knob
press
in the spring-loaded outer
disc
and
attach the
knob
by
its three claws over the focusing knob. The extension
knob also carries a
double film indicator
to show
the type and the
speed of
the film in the camera.
The
extension
knob is
available
calibrated in either feet or
metres.
The knob
will fit all but the earliest
Rolleis.
