Kodak Projection Ektanar Lens 5 Inch f/3.5 Slide Projector Lens 35mm

The Kodak Projection Ektanar is a fixed-focal-length projection lens made by Kodak for use with their slide projectors. This example carries a 5-inch (approximately 127mm) focal length and a maximum aperture of f/3.5, making it a relatively fast lens suited for larger-screen projection or longer throw distances. The barrel is black anodized metal with Kodak's engraved lettering on the front ring and the focal length and aperture marked near the front element.

Applications

The Projection Ektanar lens line was designed for Kodak's family of 35mm slide projectors, including the long-running Carousel and Ektagraphic series. These projectors were standard equipment in schools, universities, corporate training rooms, and audiovisual departments from the 1960s through the 1990s. A 5-inch focal length is well suited for medium-to-long throw distances — projecting a larger image from farther back in a room — compared to the more common 4-inch or 3-inch lenses used at closer range. Today, Carousel and Ektagraphic projectors remain in use among photographers, archivists, and hobbyists who still work with slide film, and replacement Ektanar lenses in good condition are sought after for keeping these machines running. The f/3.5 aperture provides adequate light-gathering for a reasonably bright image at the longer throws this focal length is used for.
