TYPE: 35 mm TTL/AEC SLR (Through-The-Lens Metering.
Automatic Exposure Control Single-Lens Reflex) FILM: Standard 35 mm 20 or 36 - exposure cartridges FORMAT: 24 x 36 mm STANDARD LENSES: Hexanon AR 50 mm f/1.7 (6 elements, 5 groups) Hexanon AR 50 mm f/1.4 (7 elements, 6 groups) Hexanon AR 57 mm f/1.2 (7 elements, 6 groups) Minimum Focusing Distance: 18" with f/1.7, f/1.4 and f/1.2 All Standard Lenses Incorporate AE-Lock, Color-Dynamic Lens Coating LENS MOUNT: Konica Bayonet type with positive lock, 47 mm diameter FLANGE/FILM DISTANCE: 40.5 mm APERTURE CONTROL SYSTEM: Fully Automatic exposure control (AEC) system (f/1.2 to f.16) with all Hexanon AR lenses. Integral Depth-of-Field Preview Control SHUTTER: Metallic-Foil vertical-scanning Copal Square-S with extended flash synchronization capability SHUTTER SPEEDS: B, 1 to 1/1000th second in standard geometrical progression; Time exposures possible without separate accessories. Non-Rotating (during exposure) shutter speed dial FLASH SYNCHRONIZATION: Optional "hot" accessory shoe provides "X" synchronization with cordless flash units, permits use of electronic flash at 1/125th second (or flashcubes to 1/30th second). Separate, built-in PC outlets for cord-type flash units permit "X" synchronization to 1/125th second, all "M"-type bulbs (including flashcubes) at all speeds. Safety interlock prevents electrical shock at PC outlets even if 'hot shoe' flash is engaged SELF-TIMER: Variable-delay to 10 seconds. Locking mechanism prevents accidental use. Timer locks up mirror, stop down lens diaphram at beginning of cycle to eliminate potential vibration at time of exposure VIEWING SYSTEM: Single-Lens Reflex type shows exact image recorded on film. Coated eye-level pentaprism shows upright, unreversed image. Image magnification 0.78x with 50 mm lens. Image seen corresponds to 92% of actual field, to insure that entire image within finder is recorded even with mounted 2x2" transparencies FOCUSING SCREENS: Standard Konica Microdiaprism screen, optional Konica Split-Image Rangefinder type IN-FINDER READOUTS: "Control-Center" viewfinder shows mode of operation (auto or manual), exact shutter speed in use, exact lens aperture in use, maximum aperture of lens in use, under/over-exposure zones, match-needle alignment mark, exposure indicator needle, battery-test indicator, meter sensitivity-range indicators REFLEX MIRROR: Coated first-surface type. Oversize design prevents image cutoff within finder even with bellows extensions at 1:1 magnification. Mirror automatically retracts as it lifts, thus permits use of extreme wide-angle lenses with unrestricted reflex viewing. Instant-return prevents image blackout after exposure EXPOSURE CONTROL SYSTEM: Fully Automatic Exposure Control (AEC) system incorporating variable-angle thru-the-lens metering by twin CdS cells housed within pentaprism. System permits: * Full-Aperture Metering and Automatic Exposure Control with all Hexanon AR lenses, * Stopped-down Aperture (Match-Needle) Metering with all manual, pre-set, or non-AE lenses. Shutter-speed preference system insures professional control METER POWER SOURCE: Two 1.35V mercury energy cells (Mallory Type PX-675 Photographic); built-in battery test circuit. Integrated Meter On-Off/Shutter Lock switch conserves battery energy when camera not in use METER 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 markers within viewfinder, appearing if coupling range is exceeded in extremely dim or bright light FILM SPEED CAPABILITY: ASA 12 to 3200 (DIN 12 to 36) EXPOSURE 'MEMORY' (hold) DEVICE: Slight pressure on shutter release (or activation of self timer) memorizes exposure reading LOADING: Konica Insta-Grip Loading (IGL) system incorporating multislot, self-locking take-up spool FILM TRANSPORT: Single-stroke lever automatically advances film, cocks shutter, activates exposure counter, prevents unwanted double exposures in fast 162º travel. Transport lever returns to "ready" position 30º away from camera body to enable continuous eye-level shooting. Oversized plastic tip provides extra comfort, prevents thumb from slipping away from lever MULTIPLE EXPOSURE CAPABILITY: Spring-loaded multiple exposure switch permits use of transport lever to re-cock shutter without advancing film or exposure counter, for creative special-effects work. System also permits infinite number of intermediate-speed "Time" exposures (1-1/4 seconds, 1-1/2 seconds, 2 seconds, 2-1/4 seconds, etc.) by exposing frame two or more times at one-second (or one-second plus any other speed) SHUTTER-READY INDICATOR: Signals Green when shutter has been cocked, red when uncocked EXPOSURE COUNTER: Indicated number of frames exposed, automatically resets to "Zero" when film is changed UNLOADING: Oversize rapid-rewind crank permits rewinding in seconds; self-locking rewind release button, automatically returns to correct position for film transport when transport lever is activated. Cutaway film cartridge chamber allows cartridge removal without raising rewind crank DIMENSIONS: With standard lens: 6" (wide) x 3-3/4" (high) x 3-3/4" (deep). Without lens: 6" (wide) x 3-3/4" (high) x 1-3/4" (deep) WEIGHT: Body only 26 ozs. With f/1.7 lens, 35 ozs. With f/1.4 lens, 36 ozs. With f/1.2 lens, 42 ozs. |
