History and technical features 



Type: 35mm single-lens reflexes with match-needle/manual exposure control.

Lens mount: Minolta SLR bayonet, 54 degree rotating angle; coupling for full-aperture metering and automatic diaphragm control with "MC" lenses (stop-down metering used for other Rokkor lenses); button for depth-of-field preview and stop-down metering.

Light-metering: Full-aperture TTL type with overlapping readings taken by 2 CdS cells mounted on pentaprism and circuited to provide optimum exposure in both flat- and most contrast-lighted situations; stop-down metering also possible.

Film-speed range: ASA 6 to 6400 set by selector on shutter speed dial.

Power: One 1.35V mercury cell, Mallory PX-625 or equivalent, contained in camera base.

Exposure control: Turning shutter-speed dial and/or lens aperture ring to align follower with meter needle visible in finder yields proper exposure according to metering system indication at the film speed set. Alignment may be disregarded for exposure adjustment or full manual control. Metering and match-needle exposure range: EV 3 to EV 17 (e.g: 1/4 sec at f/1.4 to 1/1000 at f/11) at ASA 100 with f/1.4 lens.

Shutter: Horizontal-traverse mechanically controlled focal-plane type; speeds 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, and 1/1000 sec plus "bulb" setting.

Mirror: Oversize quick-return type (PO value: 138mm; finder image cutoff negligible even with 1600mm f/11 RF Rokkor extreme telephoto).

Finder: Eye-level pentaprism type showing 94% of 24x36mm film-frame area.
Magnification: 0.83X with 50mm lens focused at infinity.
Mat-Fresnel-field focusing screen with centered focusing aid;
3mm microprism spot in SR-T 100b and 101b, 2.5mm horizontal split-image spot surrounded by 1.5mm microprism band on SR-T 303b.
Meter needle and circle-tipped follower for match-needle exposure control, coupled metering-range limits, and battery-check indication all silhouetted within the viewfield;
shutter-speed scale and setting indicator visible below the frame in SR-T 101b and 303b;
lens aperture set on most Minolta lenses appears above the fame in SR-T 303b.

Flash sync.: X or FP delay: Through separate PC terminals on SR-T 100b; 101b adds an X-sync. hot shoe; through single PC terminal or hot shoe on 303b; X contact: Electronic flash synchronizes at 1/60 sec. and all slower settings including B; FP contact: FP flashbulbs synchronize at all settings through 1/1000 sec. Hot shoe contacts disconnected when a unit not inserted.

Film advance: Lever type, single- or multiple-stroke, 150 degree winding angle after 20 degree engaged movement to allow offsetting from body. Advancing-type exposure counter resets automatically when camera back is opened.

Self-timer: On SR-T 101b and 303b only; lever-type, approx 10 sec. maximum delay.

Other: 4-slot take-up spool; ASA/DIN conversion scale on back cover; conversion scale surrounded by memo holder on SR-T 101b and 303b.

Dimensions: 145 x 47.5 x 95mm (5-3/4 x 1-7/8 x 3-3/4 in.) without lens.

Weight: SR-T 100b: 690g (24-5/16 oz.),

Lens: 50mm f/2 MC Rokkor
Type: Meter-coupled Gauss-type standard lens
Construction: 6 elements in 5 groups
Angle of view: 46 degrees
Coating: Minolta Achromatic
Min. focusing dist.: 0.5m (1.75 ft)
Diaphragm: Fully automatic, meter-coupled
Aperture scale: 2, 2.8, 4, 5.6, 8, 11, 16 (full and half-click stops)
Filter thread diam.: 55mm
Dimensions: 65mm x 35.5mm long (2-9/16" x 1-3/8")
Weight: 240g (9-7/16 oz.)
