Lens mount adapter Pixco FUJI/FUJIFILM X to C-Mount M25 (model SB3153)

The Pixco FUJI/FUJIFILM X to C-Mount M25 adapter (model SB3153) is a mechanical lens mount adapter that enables fitting C-Mount M25 lenses to Fujifilm X‑mount mirrorless camera bodies. It preserves optical alignment and flange distance so that industrial, CCTV and cine-style M25 optics can be physically mounted on X‑mount cameras for experimental optics, video capture, machine vision tests or specialized photography setups.

Advantages

This adapter provides a precise mechanical interface between FUJI/FUJIFILM X bodies and C‑Mount M25 lenses without electronic communication. Constructed for stable attachment, it helps maintain focus reliability and repeatable positioning when using non-native lenses. The compact, lightweight design minimizes added bulk while allowing access to a wider range of manual and specialty optics for creative or technical applications.

Suitable for

• Experimental and creative photography using M25 or C‑Mount optics
• Machine vision and inspection setups that require Fujifilm X bodies
• Video and cine projects using compact M25 lenses
• Adapters for CCTV or surveillance lenses on mirrorless cameras

Key specifications

• Mount conversion: FUJI/FUJIFILM X camera body to C‑Mount M25 lens mount
• Material: metal construction for mechanical stability
• Function: purely mechanical adapter, no electronic contacts or aperture control
• Compatibility: supports manual focus and manual aperture lenses designed for C‑Mount M25
• Form factor: compact, lightweight profile to minimize added length and weight

How to use

Align the adapter with the FUJI/FUJIFILM X mount on the camera and rotate into the locking position following the camera’s mount instructions. Attach the C‑Mount M25 lens to the adapter by threading or bayonet engagement as appropriate, and confirm secure mechanical connection before powering on the camera. Because the adapter does not transmit electronic signals, set exposure, focus and aperture (if available on the lens) manually on the camera or lens. Verify focus using the camera’s focus aids, focus peaking, or magnified live view.

Usage recommendations

Use this adapter with lenses that have appropriate image circle coverage for your Fujifilm X sensor to avoid vignetting. For critical work, test focus accuracy and perform lens calibration if necessary. Handle the adapter and lens carefully to avoid cross‑threading and ensure a dust‑free environment when changing optics.
