Minolta's mid X-series — X-570/X-500, aperture-priority auto, TTL flash, electronic shutter, MD mount, 1983.
The Minolta X-570 was introduced in 1983 as a mid-range X-series model, sold as the X-500 in Europe and other markets. It sat between the X-370 and X-700 and added a fuller finder display and TTL flash metering over the entry body.
It is an electronically controlled 35mm SLR on the Minolta SR/MC/MD bayonet, here labelled Minolta MD. It uses an electronic focal-plane shutter and offers aperture-priority automatic exposure along with manual control, but no program mode. Metering is through-the-lens and centre-weighted, the finder shows both the metered and the manually set shutter speed via LEDs, and the body supports TTL flash metering. Because the shutter is electronically timed the camera needs a working battery to fire.
The X-570 suits students, travellers and general users who want aperture-priority automation with a helpful full finder readout and TTL flash in a light body. Some users prefer its finder display to the X-700's, though it omits the program mode and depends fully on its electronics.
On the used market, test the shutter across its range and confirm the auto exposure system responds 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, LEDs, TTL flash and auto system, be aware ageing capacitors and electronics can fail, and clean the battery contacts. Inspect the prism for haze, feel the advance and rewind, and note the body will not fire without a working battery.
