MK-EFTR-A

It works, and it works very well! Very durable, made of metal. It is very easy to install. The lens is installed smoothly, but with tension and holds without backlash. All functions from camera to lens work perfectly. The quality is much better than I expected. The image quality is amazing. I am very pleased with the purchase. Now I can use my lenses on the new camera.

This is a great adapter to use your older lenses with the new RF system from Canon! I switched to the EOS R camera last year and love the new mirrorless cameras from Canon. I have so many EF mount lenses that I have collected over the years and didn't want to sell them and fully switch. This adapter allows me to use my older lenses on the EOS R mount system. I like this adapter for three reasons. It is works perfect with my EF mount lenses. I was worried my EF lenses wouldn't work as smoothly or quickly with the autofocus works amazing. It's like having a native RF mount lens on the camera. An example is, I can use my EF 24-70 MK2 2.8 L on my EOS R and it works perfectly. I tested it vs my Canon adapter and from what I could tell, it worked the same. Price & Availablity! It is half the price of the Canon adapter. There is a shortage of adapters lately. I'd say over the last 3 months it's hard to find the Canon RF to EF adapter, this one was in stock and is a great option. Build Quality. It feels solid and has a rubber gasket for protecting your lens and body from dust. It's slightly lighter and I'm always happy so shave off weight from my camera setup. I picked this up and keep it on my 35mm 1.8 lens. I love having it always adapted. It makes switching lenses so quick and easy. If you need an adapter for your EOS R, R5, Rp, or R6...This is a great option.

Perfect adapts my older lens

Works great. safes me bunch of money buying EF lenses

This works great on the Canon R50

Fits my OM-3 snuggly and attaches to my EF 35-350. Autofocus works well but lens moves a bit once attached to the adapter. Despite some “clicky” back and forth movement it seems to function just fine.

Great product.

Durability - strong Picture qaulity - not affected Compatibility - exactly as directed fits many of my lenses. Ease of use - super easy to use Works well Mountability - just like any other lens.

Well made, It works and is a good price.

es compatible con la camaram pero genera una viñeta negra en las fotos

Bon achat

This just works, no issues whatsoever. I use it for my eos r7 with my Canon EFS 17-55, ef 70-200 f4, and ef 85 f1.8

Used it to attach a Sigma 150-600mm to my Canon R7. Holds the large lens securely to the camera, with only just a slight bit of rotational play. All electronic functions work perfectly, just the known close range AF tracking issues between this lens and camera body, but that isn't the adapter's fault.
