MINOLTA X-700 - Technical Details
Type: Electronically governed 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; coupling for full-aperture metering, finder display input, and 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 incorporating 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-travers focal-plane type; electronicall conrolled stepless speeds 1/1000 to 4 sec. set automatically with endlessly rotatable selector dial locked at "P" or "A" setting of fixed speeds 1 to 1/1000 sec. or "B" set manually at detented dial indications; electromagnetic shutter release locks when voltage too low for proper operation.Metering: TTL center-weighted averaging type, by silicon photocell mounted at rear of pentaprism for available light, measured full aperature for normal finder display, then at taking aperature 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 that locks at 1/3-EV increments. Exposure-adjustment control: Up to +- 2 EV continuous adjustment of P,A, or M exposure by dial that locks at zero position and each 1/2-EV setting. Mirror: Triple-coated oversize instant-return slide-up type. 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, FDC signal, mis-set lens warning in P mode, battery check, f-number set with MD or MC lenses, and exposure-adjustment 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 show.Read full review
