Aperture Control System:
Automatically sets correct f/stop (or fractional f/stop) with all Konica Automatic
Hexanon lenses
Shutter:
Metallic, vertical-scanning Copal Square-S
Shutter Speeds:
Convenient top-mounted selector for all speeds from I second to 1/l000th second plus "B" (for
time exposures)
Flash Synchronization:
Electronic flash synchronization at all speeds to and including 1/125th second.
Positive PC flash cord terminal. Optional Konica Accessory Clip 3 attaches to camera eyepiece.
Viewing System:
Parallax-Free Single Lens Reflex System. Coated, eye-level pentaprism shows upright,
unreversed image; apparent magnification 0.78X with 50mm lens.
Focusing Screen:
Standard Konica Microdiaprism screen.
In-Finder Readouts:
"Control-Center" viewfinder shows vital data at a glance: exact lens aperture being set
automatically; maximum aperture of lens; under/over-exposure ranges; match-needle indicator for semi-
automatic operation.
Reflex Mirror:
Oversize, coated mirror prevents image cutoff in finder even with bellows extensions at 1:1
magnification. Mirror design permits automatic operation even with extreme wide-angle lenses. Instant-return
mirror action prevents image blackout aRer exposure.
Exposure Control System:
Fully Automatic Exposure Control (AEC) system selects
and sets
correct lens
aperture (or fractional aperture) automatically, based on information obtained from dual through-the-lens CdS
cells located in pentaprism. Metering system automatically matches acceptance angle to match focal length of
lens: provides virtual spot readings with wide-angle lenses, center-weighted readings with standard lenses,
intergrating readings with telephoto lenses.
Meter Power Source:
Two 1.35 Volt mercury photographic batteries, photographic type (Mallory PX-675,
Everready EPX-675, or equivalent).

Meter Coupling (Sensitivity) Range:
98,304:1 (EV 1.5-EV 18 with f/1.2 lens and ASA 100 film). Meter
coupling range automatically indicated by red flag in viewfinder, which shiRs if coupling range is exceeded by
existing illumination with film type in use.
Film Speed Range:
ASA12-3200(Equivalent DIN 12-36 for European films).
Exposure "Memory" Lock:
Memorizes and holds exposure reading to allow precise meter operation in backlit
or spotlit situations; operates via shutter release.
Loading:
Konica Insta-Grip Loading (IGL) system use~ multi-slotted take-up spool to grip film securely.
Film Transport:
Single-stroke lever automatically advance~ film, winds shutter, counts exposures, and
prevents unwanted double exposures. Lever returns to "ready" position away from camera body to permit
continuous operation at eye-level. Oversize plastic grip on lever provides finger tip control, extra comfort.
