Lens Mount Adapter Pixco for Canon EOS R (RF) to Nikon G — Pixco SB4842

The Pixco SB4842 lens mount adapter enables mechanical mounting of Canon EOS R (RF) lenses onto Nikon G-mount camera bodies. This adapter provides a physical connection that holds RF lenses securely on Nikon G cameras, allowing the use of Canon RF glass where native Nikon optics are not available. The adapter does not provide electronic communication between lens and camera; aperture control, focus, and exposure metering depend on the lens design and camera capabilities when using manual or mechanical controls.

Advantages

The adapter is compact and lightweight, designed to preserve correct flange distance and stable lens alignment when attaching RF lenses to Nikon G bodies. Because it is a mechanical adapter without electronic contacts, it is simple in construction and compatible with a broad range of RF lenses that have manual aperture or mechanical control rings. The absence of electronics eliminates issues related to unsupported communication protocols and reduces potential points of failure.

Suitable for

• Photographers who own Canon EOS R (RF) lenses and want to use them on Nikon G-mount cameras
• Artists and experimental photographers exploring cross-system lens characteristics
• Technical or studio setups where manual aperture and focus control are acceptable
• Rentals or temporary use when switching between camera systems

Key specifications

• Mount conversion: Canon EOS R (RF) lens to Nikon G camera mount
• Type: Mechanical adapter without electronic contacts
• Weight: compact, lightweight construction for minimal added bulk
• Material: durable metal and/or alloy body for secure lens attachment
• Optical elements: none — maintains native lens optical path
• Compatibility: supports manual aperture control and manual focus on compatible lenses and camera bodies

How to use

Attach the adapter to the rear of a Canon EOS R (RF) lens by aligning the lens release marks and turning until it locks in place. Then align the adapter with the Nikon G camera mount and turn until it clicks into the camera body mount position. Set the lens aperture and focus manually on lenses that provide mechanical control; for lenses without a mechanical aperture ring, use the camera body settings if the camera supports controlling a non-electronic lens, or rely on manual exposure settings. Confirm secure attachment before use and avoid forcing mounts; remove the adapter by reversing the procedure.

Usage recommendations

For predictable results, test lens and camera combinations before critical shooting. Use a tripod or stable support when working with manual focus lenses and consider focus peaking or magnified live view (if available) to assist precise focusing. Be aware that functions such as autofocus and electronic aperture control will typically not be available with this mechanical adapter.
