    It's good adaptor to use for your old lens. Not a really good build. It's a decent buy.

    It’s free, at least when you purchase the EOS R. Definitely greets for anyone within the Canon ecosystem.

    Good adapter for ef lenses but keep in mind that lenses that have a white dot will be limited to certain functions at least in the rp model

    Don’t buy any lens at BestBuy. 15% restocking fee. What risk it when Amazon has no fee!

    Excellent Canon Lense adapter

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I am very happy that this Canon EF to RS exist. I can continue using my old Canon EF lenses and taking great pictures with my Canon R8 mirrorless camera. This adapter is super easy to mount, well built and it has saved me over 3 grants since I own three Canon EF lenses and I don't have to buy any new Canon EOS R lense. This is a great investment from my perspective.

    Great product, works perfectly well. I used this on my Canon EOS R7 and a 24-70 mm lens and it works like a charm! Tried another product and it didn’t work as well!

    This worked perfectly for using my EF lenses on my RF Camera! I bought two of them! One for each camera! Such a great investment to be able to utilize all my lenses
