Minolta's XD-s — dual-auto XD with eyesight-correction eyepiece, electronic shutter, MD mount, 1981.
The Minolta XD-s was a 1981 variant of the XD line fitted with an eyesight-correction feature at the viewfinder eyepiece. It kept the XD series' dual automatic exposure capability and worked best with MD lenses that pass aperture information to the body.
It is an electronically controlled 35mm SLR on the Minolta SR/MC/MD bayonet, here labelled Minolta MD. It uses an electronic vertical metal focal-plane shutter and offers aperture-priority auto, shutter-priority auto and manual exposure. Metering is through-the-lens and centre-weighted, and the eyepiece includes built-in dioptre adjustment. Because the shutter is electronically timed it needs a working battery to fire, with only a limited mechanical speed for emergencies.
The XD-s suits users who want both automatic modes plus built-in eyesight correction in a compact electronic body for general, travel and portrait work. It offers the same automation as the XD-5 with the added eyepiece adjustment, though it depends on healthy electronics and pairs best with MD-series lenses.
On the used market, test the metal shutter across its range and confirm both auto modes respond to changing light. Foam light seals and mirror-damper foam commonly perish and usually need renewal. As an electronic body it relies on its circuitry, so check the meter and auto systems, be aware ageing capacitors and electronics can fail, and confirm the dioptre eyepiece adjustment moves. Inspect the prism for haze, feel the advance and rewind, and note the body will not fire normally with a dead battery.
