Manufacturer description #1

camera with a "built-in memory!"

new... automatic ASAHI-PENTAX K combines rapid wind design with penta-prism viewing, instant return mirror... and automatic lenses!

Here's the famous single lens reflex camera that ended photographic black-out... now with a built-in memory system that makes exposure AUTOMATIC! You see - shoot - see again before completing the trigger motion! Now ...the lens joins the shutter in this amazing action: when you wind for the next exposure, when you choose your shutter setting and select your lens aperture, trip the shutter, THE LENS STOP DOWN AUTOMATICALLY... the mirror flips... the shutter closes... the mirror returns ...INSTANTLY! Improved shutter system ... to 1/1000th. Most compact of all bodies! New 6-element f 1.8 lens! New improved Fresnel-lens brightened ground-glass with bulls-eye targeting! Takumar lenses from 35mm to 1000mm compatible with most single lens reflex cameras. ASAHI-PENTAX K with Takumar 6-element automatic f 1.8 lens completely ends the photographic black-out $249.50.

Manufacturer description #2

TYPE: Penta-prism single lens reflex, with automatic diaphragm.

FILM SIZE: 35mm film.

PICTURE SIZE: 24mm x 36mm.

FOCAL PLANE SHUTTER SPEEDS: T, B, 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000 sec. Synchronized for regular flashbulbs and electronic flash. Special "X" setting on high speed shutter dial for use with electronic flash

VIEWING AND MICRO-SPLIT IMAGE FOCUSING: Viewing and focusing are done through the penta-prism viewfinder with its built-in, 4-power magnifier and image-brightnening Fresnel lens. fast, precision focusing is made easy by the use of a micro-split image circle in the center of the penta-prism. Minor errors in focus are greatly magnified in concentric circles to permit rapid, exact correction.

REFLEX MIRROR: Instant Return Mirror capitalizes on the human eye's image retentiveness to aid in the photographic follow-through.

FILM TRANSPORT AND REWIND: Single-stroke rapid transport lever automatically winds film and cocks shutter. Double exposure prevented. Film rewind crank speeds film take-up.

FILM TYPE GUIDE: Color-coded to aid in film identification with ASA range from 10-800, or with DIN range from 11/10-30/10.
