Attach any EF- or EF-S-mount lens to your EOS R mirrorless camera using this EF to EOS R Mount Adapter with Variable ND Filter from Neewer. Designed to expand your range of compatible lenses, the adapter has electrical contacts that retain full autofocus and image stabilization capabilities while also allowing transfer of Exif data to your camera. This adapter includes a drop-in variable neutral density filter for greater control over your exposure settings.

Canon EF/EF-S Lens to EOS R Camera    Includes Drop-In ND3-ND500 Filter    Maintains AF and Image Stabilization    Includes Front and Rear Caps

The included drop-in variable neutral density filter has an ND3-ND500 range, offering 1.5 to 9 stops of adjustment. The degree of density is easily controlled by rotating the filter's wheel, helping you to predetermine the additional exposure length required. By increasing your aperture or slowing your exposure time, you are able to control depth of field and convey movement more easily. A clear filter is also included for when no VND filter is required.

The full metal body of the adapter is robust and highly durable. In addition, the VND filter features multiple layers that make it water-repellent, dust- and oil-proof, and scratch-resistant.

Compatible with Canon EOS R cameras, including the R, Ra, RP, R5, R6, R3, C70, R5 C, R7, R10, R6 Mark II, R8, and R50 models.
