Canon's RF 2x extender boosts your lens' focal length by 2 times, launching you towards your chosen subject, highlighting each and every detail. Developed specifically for use with Canon's full frame EOS R line up, such as the Canon R5, having that extra length lends itself to those shooting sports, wildlife and reportage photography. The teleconverter features high refraction and low dispersion glass which helps to control the curvature of field and chromatic aberrations. Advanced lens coatings have also been implemented that help to reduce ghosting, all of which will ensure a high-quality and highly detailed final image.
