Adaptér objektivu Canon Canon Mount Adapter EF-EOS R

Connect EF-mount lenses to EOS R system cameras using the Lens Adapter Canon Mount Adapter EF-EOS R. Designed to preserve the performance and electronic communication of EF lenses when mounted on RF-mount bodies, this adapter measures 24 mm in length, weighs 110 g and has a black finish. The adapter is weather-sealed against dust and moisture to support outdoor and location work while retaining autofocus and exposure control between lens and camera.

Its compact and lightweight design (24 mm length, 0.11 kg) keeps handling balanced and minimizes additional bulk on the camera. Weather-sealing helps protect the connection from dust and moisture during field use.
