Canon lense adaptor
Simple and effective coupler at a very reasonable price (by Canon standards). Rapid service.

Worth the cost.
When using canon, this adapter allows me to use EF lenses on a canon R series camera, expanding the opportunity to buy a range of lenses both EF and RF. Feels tight when putting it onto the camera but nothing to be concerned about, as it is secure and works perfectly.

Use with no loss of quality.
No loss of quality, works fine. Donât go with cheaper 3rd party ones, they sometimes donât transfer all functionality. I can definitely recommend this.

Works a treat
Hello…i’ve had this adapter for a while now and it works a treat with my EF lenses, primes and zoomy ones. Image quality is spot on Theres no wobble and everything attaches solidly. As far as i can say its weather sealed, was out in some torrential rain in the North East and there were no misfunctions. To those who say it makes the lens stick out more (of course it does its an adapter after all) but not in any way thats going to effect photographs or moving about, no way. Its saved me sooo much money not having to sell my existing EF lenses to buy replacements for my RF camera. Good Stuff….Bye.

Well I managed to purchase this adapter during a brief 25% off sale, otherwise at the normal price I would have considered it too expensive for an amateur photographer with limited budget. Already I have used the adapter with CPL on my newish Canon EOS R6 during some outdoor photo shoots and have found it to be excellent. So easy to adjust since the adjustment wheel sits near to the camera body rather than at the extremity of the lens. Works with all my EF glass since it’s in the adapter. Have ordered and waiting to receive the clear filter so I can keep this adapter on the camera all the time and simply change filters to suit the shoot location, time of day etc.I could not see any unexpected colour changes in the pics taken using this CPL. Provided some beautiful mid-to-deep blues in the daytime sky. For this adapter, the ND filter is way, way over-priced so will probably wait for a special with a decent discount if I decide to purchase it. It’s a great shame Canon don’t offer these accessories at a more reasonable price and focus making their money on camera and lens sales. If you have EF glass and want to use it on RF mount, and can afford this adapter, I highly recommend it.

Oggetto originale Canon necessario per chi come me vuole continuare ad utilizzare le lenti ef sulle fotocamere mirrorless della serie R. Arriva in un comodo astuccio con tappo frontale e posteriore. Il pulsante di sgancio è preciso al pari di quello della fotocamera. Super consigliato!
