The Canon EOS R5 and R6 cameras have created a lot of excitement in the photography world, and for the tons of photographers who already have deep investments in the EF lens library, the question of whether adapted performance can keep up with professional demands looms large. This great video shows you the kind of performance you can expect in real-world usage. 

Coming to you from Jared Polin, this excellent video takes a look at adapted lens autofocus performance using an EF-to-RF adapter on the Canon EOS R5 and EOS R6 cameras. The autofocus system on the new cameras is definitely impressive, but with the expensive prices of RF lenses and existing libraries of EF lenses many photographers own, the prevailing preference may be to instead adapt. Thankfully, it looks like adapted autofocus performance is fantastic, even in demanding situations. Personally, this is definitely great news, as I personally have a large EF lens library, and beyond that, the RF lens lineup simply does not have a lot of more esoteric options available yet, such as wide-aperture super-telephoto lenses, and you also get the additional features of the mirrorless system, such as eye and face tracking. Check out the video above to see what you can expect.
