M42 to Canon FD Mount Lens Adapter

The M42 to Canon FD Mount Lens Adapter allows you to mount classic M42 screw-mount lenses onto Canon FD-mount SLR bodies. This is an early bayonet-style adapter, which means it locks into the FD mount securely and provides a stable, reliable fit for manual focus lenses from brands like Pentax, Zeiss, Yashica, and more.

This style of adapter is best used in stop-down metering mode — meaning you’ll set your aperture manually on the lens, and then the camera will meter with the lens already stopped down to that value. It’s a simple and effective way to bring vintage lenses into your Canon FD shooting workflow, whether you're using a film body like the AE-1, A-1, or F-1.

Please note:
This adapter may not work correctly with Fujica M42 lenses, which often use a non-standard aperture control pin. It should, however, be fully compatible with most other standard M42 screw-mount lenses.

Condition: Excellent

• Bayonet ring locks securely with no wobble
• Threads are smooth and clean
• Shows very light cosmetic wear from normal use
• No dents, damage, or misalignment

A great little tool for any Canon FD shooter looking to explore the expansive world of M42 lenses — especially those wanting to adapt Takumars, Helios 44s, or vintage Zeiss glass.
