CAMERA TYPE: 35 mm TTL (Through-the-Lens metering), AEC (Automatic Exposure Control), SLR (Single-Lens-Reflex) FILM: Standard 35 mm 20 or 36 exposure cassettes FORMAT: 24 x 36 mm STANDARD LENS OPTIONS: Konica Hexanon AR 50 mm f/1.7 (6 elements, 5 groups) Konica Hexanon AR 50 mm f/1.4 (7 elements, 6 groups) Konica Hexanon AR 57 mm f/1.2 (7 elements, 6 groups) MINIMUM FOCUSING DISTANCE: 17.4" from film plane LENS MOUNT: Konica Bayonet (47 mm diameter) FLANGE/FILM DISTANCE: 40.5 mm 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 1 second to 1/1000th 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 50 mm 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 after 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, integrating 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 shifts of coupling range is exceeded by existing illumination with film type in use FILM SPEED RANGE: ASA 12 - 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 uses multi-slotted take-up spool to grip film securely FILM TRANSPORT: Single-stroke lever automatically advances 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 fingertip control, extra comfort UNLOADING: Oversize rapid-rewind crank permits rewinding within seconds; cutaway film cassette chamber allows drop-out cassette removal DIMENSIONS: With standard lenses: 5.9" wide, 3.9" high, 3.6" deep Body only: 5.9" wide, 3.9" high, 1.8" deep WEIGHTS: Body: 24 oz. Lenses: 50 mm f/1.7: 8.5 oz. 50 mm f/1.4: 10.2 oz. 57 mm f/1.2: 16.2 oz. |
