## Long description

The Pentax Mount Adapter K enables mounting screw-thread Pentax lenses on Pentax K-bayonet camera bodies. It provides a simple mechanical connection that preserves aperture-priority exposure and supports manual lens operation. The adapter has a silver finish, is lightweight (16 g) and compact (80 mm × 92 mm), and is manufactured in Japan.
Advantages
This adapter permits use of Pentax "S" screw-mount (42 mm) lenses on cameras with the Pentax K bayonet, keeping aperture-priority metering and full manual control of focus and aperture. Its lightweight metal construction and compact size make it easy to carry and use without adding significant bulk. Made in Japan for consistent build quality.
Suitable for
Photographers who want to use vintage Pentax screw-mount lenses on K-mount camera bodies
Manual-focus shooting and creative optics experiments
Collectors and users adapting older lenses for modern cameras

Operation: Manual focus and manual aperture control with aperture-priority metering maintained
Finish: Silver

How to use
Align the screw-thread lens with the adapter's internal 42 mm thread and fully secure the lens by turning it clockwise until it seats. Attach the adapter to the camera body by aligning the K-bayonet index marks and twisting until it locks into place. Set the camera to aperture-priority or manual exposure mode; aperture control and focus are performed directly on the lens. Because the adapter provides only a mechanical connection, electronic communication and autofocus are not available.
Usage recommendations
Check that the lens and camera contacts are clean before mounting. Use manual exposure modes when working with adapted lenses and confirm metering on the camera; for critical focus, use magnified live view or focus peaking if available.
