Projection Lenses

Slide and image projection lenses | Projection formats specified by each lens, including 24 × 36 mm slides
Projection lenses form an enlarged image of a slide or other source on a screen. The projector supplies the lens carrier and focusing travel. This catalog category identifies that application; it does not imply one interchangeable mechanical standard.
Barrel diameter, carrier engagement, and focusing arrangements vary between projectors and lens generations. The original five-element Leitz Colorplan belongs here without implying compatibility with later Leica P2 carriers or a camera bayonet. The associated image-format metadata describes the slide gate.
