PHOLSY Lens Mount Adapter Manual Focus Compatible with M42 42mm Mount Lens to Canon RF Mount Camera Body

Rediscover the character of classic glass with the PHOLSY M42 to Canon RF lens mount adapter. Designed for photographers who appreciate the tactile control and distinctive rendering of vintage optics, this adapter lets you pair M42 42mm screw-mount lenses with your Canon RF mount camera body—opening up a world of creative lens combinations without investing in new RF lenses.

Built for reliability and consistent results, the PHOLSY adapter delivers a secure fit and accurate flange distance so you can focus to infinity with confidence. Because it’s a fully manual adapter, it’s ideal for deliberate shooting styles—portraits, still life, landscapes, and video—where precision matters most.

• Wide compatibility: Works with M42 42mm mount lenses (note: not compatible with Mamiya and Fuji 42mm lenses) and Canon RF mount cameras.
• True manual experience: No electronic contacts—no autofocus, no auto-aperture, and no EXIF transfer. Set focus, aperture, and exposure manually for full creative control.
• Premium build: Hardened aluminum and copper construction with an anti-reflective, matte interior to help reduce internal reflections and maintain contrast.
• Easy mounting: Quick to attach and remove for smooth lens changes.

If your camera displays “lens is not properly installed,” enable Release without lens in the menu (refer to your camera manual). Ready to bring your M42 collection back into daily use? Add the PHOLSY adapter to your kit and start shooting with timeless optics today.
