Product information

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

Key specifications

Mount type: Pentax K bayonet (camera side) to Pentax 42mm screw-thread (lens side)
Compatibility: Permits Pentax “S” screwmount lenses on Pentax K-bayonet bodies
Operation: Manual focus and manual aperture control with aperture-priority metering maintained
Finish: Silver
Weight: 16 g
Dimensions: 80 mm (width) × 92 mm (height)
Made in: Japan
Manufacturer part number (MPN): 30120
EAN: 027075003965

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.
