Minolta X700 Motor drive 1

Type: 35mm single-lens reflex AE camera Exposure-control modes: Fully programmed ("P"), aperture-priority automatic ("A"), and metered manual ("M") Lens mount: Minolta SLR bayonet of integrally lubricated stainless steel (54 degree rotating angle); coupling for full-aperture metering, finder display input, and an automatic diaphragm control, providing programmed or aperture-priority auto operation with Minolta MD lenses, aperture-priority auto operation with MC and other Minolta SLR interchangeable lenses/accessories; spring-return button for depth-of-field preview or stop-down meter readings with other than MC or MD lenses (standard lenses: MD 50mm f/1.2, f/1.4, f/1.7 or f/2) Exposure control and functions: Low-voltage, low-current computer circuit with a quartz crystal for sequential control to 1/30,000-sec. accuracy, large-scale ICs, samarium cobalt impulse-release magnets, and linear-resistance inputs) varies both aperture and shutter speed steplessly according to special "faster-speed" program in P mode, or varies shutter speed steplessly according to aperture set in A mode, to yield proper exposure for the film speed and exposure adjustment set; auto-exposure range: EV 1 to EV 18 (e.g., 1 sec. at f/1.4 to 1/1000 at f/16) at ASA/ISO 100 with f/1.4 lens; AE-lock device holds meter reading for exposure at that value regardless of subject-brightness changes Shutter: Horizontal-travel focal-plane shutter; electronically controlled stepless speeds from 1/1000 to 4 sec. Selector dial locked at "P" or "A" setting of fixed speeds 1 to 1/1000 sec. or "B" (bulb) set manually at detented dial indications; electromagnetic shutter release locks if the voltage is too low for a proper operation. Metering: TTL center-weighted averaging type, by silicon photocell mounted at rear of pentaprism for available light, measured full aperture for normal finder display, then at taking aperture for programmed/automatic-exposure setting/determination or stop-down display; by another SPC mounted with optic in side of mirror compartment for off-the-film light at taking aperture during exposure to control dedicated flash duration. Film-speed range: ASA/ISO 25 to 1600 set by dial with 1/3-EV increments. Exposure-adjustment control: Up to +- 2 EV continuous adjustment of P, A, or M exposure by dial with 1/2-EV steps. Mirror: Triple-coated oversize instant-return slide-up type mirror. Viewfinder: Eye-level fixed pentaprism type showing 95% of 24x36mm film-frame area; magnification: 0.9X with 50mm standard lens focused at infinity; power: -1D, adjustable with accessory snap-on eyepiece lenses; Fresnel-field focusing screen having artificially regular-patterned matte field plus central split-image horizontally oriented focusing aid surrounded by microprism band, interchangeable with Type P1, P2, Pd, M, G, L, S, or H screens at authorized Minolta service stations; visible around frame: mode indication (P, A, or M), shutter-speed scale (1, 2, 4, 8, 15, 30, 60, 125, 25, 500, and 1000) with LED setting indication, triangular over-/under-range LED indicators blinking at 4Hz, flash-ready signal (LED next to "60" blinking at 2Hz), FDC signal ("60" LED blinking at 8Hz of 1 sec. after correct flash exposure), mis-set lens warning (mode indication blinking at 4Hz) in P mode, battery check (by glowing of any LED when operating button touched or pressed slightly), f-number set with MD or MC lenses, and exposure-adjustment engaged indication (LED blinking at 4Hz); display and metering activated by normal finger contact or slight pressing of operating button and continue for 15 sec., except go out after shutter release. Flash sync: PC terminal and hot shoe for X sync (disconnected when no unit installed); electronic flash ("strobe") synchronizes at 1/60 sec. and slower stepless or fixed speeds or "B" setting; Class MF, M and FP flashbulbs, at 1/15 or slower settings; additional spring-loaded contacts on hot shoe for camera/flash control and finder indication in programmed automatic operation. Film advance: Manual: by lever with single 130 degree stroke after 30 degree unengaged movement; motorized: through the built-in coupler key with accessory Motor Drive 1 or Auto Winder G; release button for rewind on camera bottom; advancing-type frame counter; Safe Load Signal indicates film loading and advancing condition. Power: Two 1.5v alkaline-manganese (Eveready A-76 or equiv.) or 1.55v silver-oxide (Eveready S-76, EPX-76 or equiv.) cells contained in camera base poser both programmed/auto exposure control and manual operation; three-position main switch with indication for off, on, or on with audible piezoelectric slow-speed warning and self-timer operating indication; battery check by touching or slightly pressing operating button (LEDs do not light when cells approach exhaustion); shutter will not release when voltage too low for proper operation. Self-timer: Electronic for 10-sec. delay, with operation indicated by camera-front LED that blinks at 2Hz for 8 sec., then 8Hz for 1 sec., then remains on until shutter releases, plus simultaneous audible indication when main switch in appropriate position; engaged by switch on body, cycle started by pushing operating button, cancelable anytime before release. Other: Audible 4Hz piezoelectric warning when finder speed indication is 1/30 sec. or slower whenever finger contacts "touch switch" normally or presses operating button slightly with main switch appropriately set; integral front handgrip; detachable back with integral handgrip, memo holder, and ISO, DIN, ASA conversion table; positive 4-slot take-up spool; remote shutter-release socket Size and weight: 51.5 x 89 x 137 mm (2 x 3-1/2 x 5-3/8 in.), 505g (17-13/16 oz.) without a lens and power cells Accessories: Exclusive Auto Electroflash 280PX, Multi-Function Back; Motor Drive 1, Auto Winder G, Power Grip 2, PX strobe cords, connectors, brackets, etc., Wireless Controller IR-1; MD, MC and other Minolta interchangeable lenses and applicable Minolta SLR system accessories.
