Key Features & Specs

The Program Plus is a manual-focus camera known for its compact design and versatile exposure modes:

• Exposure Modes: Offers four modes—Programmed AE (automatic aperture and shutter), Aperture-priority AE, Metered Manual, and Programmed Auto Flash.

• Shutter Speeds: Electronically controlled vertical shutter with speeds from 15 seconds to 1/1000 second, plus a Bulb mode for long exposures.

• Lens Mount: Uses the Pentax KA mount, making it compatible with a wide range of Pentax K, KA, and Kf lenses.

• Battery: Requires two 1.5V silver or alkaline batteries (like LR44) or one 3V lithium battery to operate. Has new batteries.

Operating Tips

• Film Loading: Open the back by lifting the film rewind knob sharply.

• Battery Check: To check if your batteries are still good, set the shutter dial to AUTO and lightly press the shutter button. If the LCD in the viewfinder shows shutter speed information, they are working.

• Program Mode: To use full "Program" mode, both the camera dial and the lens aperture ring must be set to the "A" position.

The bottom of the camera also features a tripod socket, a battery compartment cover, and connections for an optional motor drive or winder.
