Meike MK-EFTR-B for Canon EF/EF-S Lens to RF Mount Cameras Auto-Focus Lens Adapter with Control Ring for Canon EF/EF-S Lenses to Canon EOS R RP R5 R6 R7 R10 C70

I have a Canon RP- the main dial is faulty, I use Av mode mostly, and this adaptor restores the physical function without needing a repair. (you could also use the touch screen of course). It worked directly without having to assign the function in the camera menu. My proviso is that I saw one YouTuber comment that eye tracking was not supported, which might be an issue if you take lots of portraits. The RP only has face tracking, but this works ok, I tested it, and other focus modes and functions are supported. The good news is that there is a usb c firmware socket included, so I imagine this issue could be solved in a future firmware update. Another nice touch is the bright red weather sealing gasket, and it is less than half the price of the Canon equivalent adaptor. UPDATE!!! My apologies! I did not have eye detection enabled on my RP- I have retested and it seems to work fine. An older adaptor without the firmware update may be a problem, solution as above- just something to bear in mind...

Works flawlessly. No reason to buy the overpriced Canon version. Note that it has no glass in it, so there is no need to worry about optical quality. It is a spacer, as the sensor in mirrorless Canon cameras is further forward, as there is no need to leave space for a mirror. It does pass through electronic signals between camera and lens, which it does well. For focus stacking the comms are more complicated, and it does this too.

Really solid adaptor. Has only ever thrown up the occasional error message but quickly rectified with a wipe down and reconnection. Has no impact on AF or quality, though the control ring is very useful as I use it for Ev on older EF lenses.

Tested with Canon EF prime lenses and an EOS RP this works great. It's a tight fit especially on the RF mount (I've had a Canon adapter in place for ages and never move it so in fairness I didn't appreciate it's quite a tight fit anyway), but it works as I hoped. I've got it set for ISO on the scale (set up via custom functions in the camera) and it works with a nice clicky effect. There doesn't seem to be any option to disable this but for ISO it's not an issue. I particularly like this because at time of purchase it's less than a third of the cost of the main brand but the functionality seems equivalent and it also works as a spare. Some reviews commented on it discharging the battery and needs a firmware update - I haven't noticed this at the time of writing.

This worked very well initially. Comparing it to the Canon equivalent it seems a little cheaper in feel but does have a weather sealing gasket. Unfortunately after almost three weeks the autofocus has stopped working for all my EF lenses and I cannot find a solution. I will have to return it. Three stars as it initially worked very well and the failure may not reflect the norm.

The lens adapter works perfectly with all my Sigma EF-S lenses, doesn't work with my Canon EF 50mm F1.8. Not a big problem as it is my cheapest lens and I still have an EOS DSLR camera. It is a much better price than the Canon equivalent.

Exactly as desribed and it works perfectly with all of my DSLR lenses on a R5 body

This was cheaper than the official adapter but it works perfectly, works with my Canon EF-s and Sigma EF lenses! Good and sturdy mountings.

il prodotto fa sicuramente una bella impressione: ben rifinito e robusto. Va benissimo con la mia Canon EOS R50 e con diversi obiettivi EF che ho provato. In tutti i casi la messa a fuoco funziona perfettamente, anche con i più datati. Anche l'anello di comando funziona bene. Ottimo acquisto!

Doet wat hij moet doen en dat voor een prima prijs.

La bague de contrôle Meike MK-EFTR-B s'adapte bien sur mon Canon R6 MK2. Je lui ai attribué le changement des valeurs ISO. Un peu trop souple pour modifier ces valeurs iso, et le moindre effleurement de celle-ci change la valeur iso. Globalement la qualité semble bonne. Mais la bague vide très rapidement la batterie du R6 MK2 même éteint. Je le savais en achetant, je savais également que la version du firmeware V 0.7 corrigeait ce problème de batterie. Mais tout est buggé sur le site constructeur. Le PDF qui ne s'affiche pas, le firmware qui n'est pas accessible ou qui est incomplet (j'ai un fichier d'extension .SKY, j'en fait quoi ? C'est vraiment pas le paradis). Bref, ni le vendeur, ni le site constructeur ne répond à mes différents mails demandant tout simplement L’EXPÉDITION DU FICHIER FIRMWARE ET LA MÉTHODE. Je suis prêt à réviser ma note et à donner la solution à autrui si une bonne âme me donne la solution.

Got this for 298aed during 11.11 sale for my R8. This one was next day delivery and I chose this over the meike just the adapter of 200 aed. I haven't used the ring but my ef lenses are working great. PS- Ef-M lens are not compatible

AFは早く反応して従来と変わらなく満足して使用してます。薄い点も気に入ってます。
