Fotodiox Pro Lens Mount Adapter for M42 Screw Mount SLR Lens to Canon RF (EOS-R) Mount Mirrorless Camera Body

Be ready to unlock the full potential of your M42 screw mount SLR lenses with the Pro Lens Mount Adapter, designed specifically for Canon RF (EOS-R) Mount Mirrorless Camera Bodies. This high-quality, durable adapter is a versatile tool for photographers, enabling them to use a wide array of lenses from brands like Canon, Nikon, Pentax, and Sony.

Designed with precision, this compact adapter ensures a secure, gap-free connection between your lens and Canon RF mirrorless camera. Its all-metal construction, enhanced with chrome-plated brass mounts, guarantees a solid fit that will not degrade over time, providing you with a reliable, stress-free photography experience.

The Pro Lens Mount Adapter is not just about durability and secure fit, it also offers manual aperture control and delivers infinity focus, allowing you to have complete control over your photography. This means you can adjust the aperture and focus manually, ensuring that you capture the perfect shot every time.

Please note that this is a manual adapter, so lens functions that rely on electronic communication with the camera body, such as autofocus, AE metering, and image stabilization, will be disrupted. 'Focus-By-Wire' lenses, such as Canon's STM or Nikon's AF-P, require power to engage the manual focus rings on the lens. Since manual lens mount adapters do not power the lens, these lenses will not be able to focus.

Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode. If your lens does not have a manual aperture control ring, the lens aperture will revert to its default position, which depending on the lens is either stopped down to its largest f-stop or opened up to its smallest f-stop.

In conclusion, the Pro Lens Mount Adapter for M42 Screw Mount SLR Lens to Canon RF (EOS-R) Mount Mirrorless Camera Body is an affordable, versatile, and high-quality tool that will help you maximize the use of your existing lens collection.
