OWNER'S MANUAL

Since the inception of through-the-Iens exposure
measuring for single-lens-reflex cameras, several systems
have been developed. Some "spot" read only a very
small part of the total area. Other systems provide an
"average" reading composed of independent measure-
ments taken by two cells which is not accurate in
high-contrast situations.
Only the Minolta SR-T 101 hasan exclusive new type
of circuit (CLC) to provide optimum reading of the
entire picture area regardlessof degree of contrast.
In addition to its more accurate exposure meter
system, your Minolta SR-T 101 is designed to handle
more easiIy, with greater speed, than other "through-
the-tens metering" cameras.
The abili y to compose, focus, set exposure and
shutter speed without looking away from the finder
makes the Minolta SR-T 101 particularly suitable for
professional photography, when operating speed is often
of vital importance.

1. Rapid-Reading Through-the-Lens Exposure
a) Exposure readings are taken with lens at full
aperture for rapid composing and focusing
regardless of subject brightness.
b) "Follower-type" needles in viewfinder show
correct exposure at it glance, witli any
combination of aperture and shutter speed.
cl Shutter speed scale is visible in viewfinder
but outside of "I ive" picture area.
d] Only the light that strikes the film is
measured, thus eliminating the need to
compensate for changes in lens focal length
or compute exposure factors for fi Iters,
bellows or other lens attachments.
2. Combine the Advantages of "Spot" and
a) Exclusive "CLC" Metering System (Contrast
Light Compensator) maintains extreme ac-
curacy regardless of lighting situation, even
with high-contrast subjects.
b) Automatically corrects for changes in light
intensity from one section of the picture
area to another. thus providing an optimum
overall reading.
cl Oversize, instant return mirror prevents
image cutoff and incorrect exposure read-
ings no matter how long the focal length of
lens.
di Unique position ing of CdS cells prevents
incorrect readings due to light entering

lensesare your thrifty choice.

Inserting the mercury battery
1. The Minolta SR·T 101 uses a 1.35v,
button-shape mercury battery for pnoto-
graphic applications (Mallory PX-625.
PX-13. Eveready EXP-625, EPX-13 or equl-
valent).
2. To install, remove the battery chamber
cover with your thumb by turning it
counterclockwise. Place the battery in the
chamber with its plus side out and replace
the cover.

CAUTION:
• Do not touch the battery terminals with
moist or dirty hands, as this can cause them
to deteriorate and make the battery inopera-
tive.
• Do not discard a mercury battery in a fire or
break it up.
• When the camera is not being used, it is
advisable to turn the battery switch on the
base of the camera to the "OFF" position.
• If the camera is not to be used for over a
month, remove the battery and store it in a
dry, cool place.
• Before putting the battery back in the
camera, clean both sides of the battery and
the contact lead of the battery chamber with
dry cloth.
