Rediscover the character of classic screw-mount glass with the PHOLSY Lens Mount Adapter, designed to pair M42 42mm mount lenses with your Canon EOS M (EF-M) mount camera body. For experienced photo gear enthusiasts aged 35+ who appreciate the tactile control and rendering of vintage optics, this adapter opens the door to new creative combinations—without replacing your camera system.

Built for reliable alignment and a confident fit, the adapter supports infinity focus and features a precision build that helps maintain image integrity. Please note: it is not compatible with Mamiya and Fuji 42mm lenses.

• Manual focus experience: No electronic contacts—shoot the traditional way with full hands-on control.
• Solid metal construction: Made of hardened aluminum and copper for durability and consistent mounting.
• Anti-reflective interior: Matte-coated inner surface helps reduce internal reflections for cleaner contrast.
• Simple to install: Easy to mount and dismount for quick lens changes in the field or studio.
• Works with M42 to EF-M setups: Ideal for adapting vintage M42 lenses to Canon EOS M cameras.

Important: Because no signals or data are transferred, autofocus, auto aperture, and electronic exposure control are not supported. If your camera shows “lens not properly installed,” enable shooting without a lens: Menu > Settings > Release without lens > Activate (see your camera manual for exact wording).
