    Works great! wish it is a bit smaller. All of my Canon EF and Sigma Art lenses works well with the adapter.

    I've been using the EF adapter with my EOS-R since the R got released. It's been pretty awesome being able to use my EF lenses on the R.

    Very useful gadget and although it adds extra length to your lens, it is not heavy, so you don't really notice the weight.

    It’s free and you can use all your Ef and ef-s lenses with a super light easy to carry around full frame camera. What’s not to like.

    This is great if you have a mirrorless camera and still have some EF lenses. It helps save money on lenses. However, note that it doesn’t work the best with EF-S lenses. It’s not ask crisp.
