    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.

    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.

    If you have bought the Canon R and have a Canon lens system you will need this in order to use your other lenses...

    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.

    Solid adapter. It allows me to keep my current lens line up. I think the price is a little steep but it does what it's supposed to do. It came late via UPS but UPS did let me know in advance and provided tracking notifications.

    This adapter does not seem to lower light or add vignette. It is very thin and not that much additional weight
