Leitz Prado — 35mm Slide Projector (Diaprojektor)

The Leitz Prado is the slide projector Ernst Leitz Wetzlar — the Leica company — built through the 1950s and 60s, and it turned up anywhere slides were shown: schools, camera clubs, lecture halls and living rooms. The line runs from the compact Prado 150 up through the 250 and 500, plus the Prado Universal and the medium-format Prado 66 for 6x6 slides, most of them paired with a Hektor or Colorplan lens.

Built the way Leitz built everything, which is why so many still project. Working units start around €15–30 and the line median sits near €70, with complete Universal outfits reaching €350. Watch what you are actually buying — the parts market is deep and cheap, so a sub-€15 listing is usually a drive belt, a lamp or a slide magazine rather than a projector, and the microscope attachments Leitz made for the Prado trade separately at far higher prices.
