## Summary description

Mechanical lens mount adapter by Pixco to mount Pentax Q lenses onto C/CS-mount (M25) camera bodies. Provides physical compatibility between Pentax Q lens mount and C/CS-mount cine or CCTV cameras without optical elements. Useful for filmmakers, videographers and machine vision setups needing manual aperture and focus control while adapting compact Pentax Q glass to compatible M25 threaded mounts.

## Long description

The Pixco lens mount adapter for Pentax Q to C/CS-mount (M25) model SB6634 is a mechanical adapter that enables mounting Pentax Q lenses onto cameras with C-mount or CS-mount (M25 threaded) interfaces. It provides a physical connection without optical elements, preserving the native manual aperture and focus of the original lens while aligning the Pentax Q optical rear to M25 threaded cine and CCTV bodies. The adapter is intended for situations where mechanical compatibility is required rather than optical correction.
Advantages
This adapter offers a straightforward, low-profile mechanical solution to use compact Pentax Q lenses on C/CS-mount bodies. By avoiding additional glass elements, it preserves the original lens image rendering and avoids introducing extra optical aberrations. Its solid metal construction ensures a secure fit and repeatable alignment between lens and camera, and the simple design keeps the flange distance stable for manual focus control.
Suitable for
Independent filmmakers and videographers using C/CS-mount cine cameras who want to use Pentax Q lenses
Machine vision and CCTV systems that require compact manual lenses adapted to M25-threaded mounts
Optical testing setups where maintaining native lens characteristics without added optics is necessary
Educational and experimental imaging projects combining Pentax Q optics with M25-compatible devices
Key specifications
Adapter type: mechanical, no optical elements
Mount conversion: Pentax Q lens mount to C/CS-mount (M25 threaded)
Material: metal construction for durability and secure fit
Compatibility: designed for Pentax Q lenses and cameras or devices accepting C-mount or CS-mount M25 thread
Functionality: preserves manual aperture and focus of the original lens
How to use
Attach the adapter to the Pentax Q lens by aligning the mount points and rotating until it locks into place according to the lens mounting action. Then screw the adapter with the attached lens onto the camera’s C/CS-mount (M25) thread until secure. Focus and aperture control remain on the lens and must be adjusted manually. Confirm that the camera sensor size and flange distance are compatible to achieve acceptable focus range; some combinations may limit infinity focus depending on body geometry.
Usage recommendations
Use the adapter with care to avoid cross-threading on the M25 connection; tighten by hand and avoid excessive force. When using on cine or imaging rigs, support the lens assembly to prevent stress on the adapter. Check mechanical fit before extended shoots and clean contact surfaces to maintain repeatable mount alignment.
