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 (54° rotating angle); 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 MD or MC

lenses (standard lenses: MD 50mm f/1.2, f/1.4, f/1.7)

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 (see p. 30) 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 ISO 100/21° with f/1.4 lens; AE-lock

device holds meter reading for exposure at that value

regardless of subject-brightness changes

Shutter: Horizontal-traverse focal-plane type; elec-

tronically controlled stepless speeds 1/1000 to 4 sec.

set automatically with endlessly rotatable selector dial

locked at "P" or "A" setting or fixed speeds 1 to

1/1000 sec. or "B" (bulb) 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 aperture for normal

finder display, then at taking aperture for pro-

grammed/automatic-exposure setting/determination or

stop-down display; by another SPC mounted with

optic in side of mirror compartment for TTL off-film

Direct Autoflash Metering at taking aperture during

exposure to control burst duration of PX-series flash

units

Film-speed range: ISO 25/15° to 1600/33° set by

ASA dial that locks at 1/3-EV increments
