Manufacturer description #1
ASAHI-PENTAX combines rapid-wind design with penta-prism viewing and instant return mirror
Here's the startling combination of major features that make the ASAHI-PENTAX one of the fastest-handling, smoothest-functioning 35mm single lens reflex cameras ever designed! Your eye focuses on a life-size image on a Fresnel-lens brightened ground glass... the single-stroke lever changes film and recocks the shutter... the amazing ASAHI-PENTAX mirror instantly returns so you repeatedly see - shoot - see again before even completing your tripper action! See ASAHI-PENTAX at your local camera store for a reflex camera revelation!
- Focal plane shutter - T, B, 1 second to 1/500
- Screw-mount pre-set diaphragm lenses from 55mm to 500mm compatible with other single lens reflex cameras
- Flash synchronized for M-F-X
- Extra-bright ground-glass with Fresnel lens
- Hidden push-button controls rewind and multiple-exposure operation
- With Takumar 6-element 55mm f2.2... $195.00.

VIEWING AND FOCUSING: Viewing and focusing are achieved by turning the distance scale ring and observing the image through the penta-prism viewfinder with its built-in magnifier and Fresnel lens. (With the 58mm lens, an approximately life-size image is seen through the viewfinder.)
REFLEX MIRROR: Instant return mirror capitalizes on the human eye's image retentiveness to aid in the photographic follow-through.
FILM TRANSPORT: Single-stroke, rapid transport lever automatically winds film and cocks shutter.
FILM REWIND: Film rewind crank speeds film take-up.
DOUBLE EXPOSURE: Coupled film transport and shutter cocking prevents double exposure. (If desired, double or multiple exposures may be made by depressing the film rewind release button located on the bottom of the camera body.
