Review: Great alternative to the original Canon adapter - I bought this adapter simply because the original Canon adapter is out of stock from all the places (no idea why is that, I searched over 2 months for the original Canon adapter without success). The adapter works great, the quality feels good and I have no complains at all.
Review: Works with ALL my lenses on my Cannon R6 - Initially I wanted the official canon adapter, however these were out of stock with no date for restocking so I bought this instead. Although I can’t compare this generic item to the branded Canon adapter, I have to say that so far I have been really impressed with what it does. All my EF lenses (Canon 100-400l mk2, Canon 100 macro, Sigma 150-600, Sigma 150 macro) work perfectly with all functions operating as I would expect. At at least half the price of the Canon adapter, I have no hesitation in recommending this item.

### ⭐⭐⭐⭐⭐ Great alternative to the original Canon adapter
*by J***E on 2 April 2021*

### ⭐⭐⭐⭐⭐ Works with ALL my lenses on my Cannon R6

Although I can’t compare this generic item to the branded Canon adapter, I have to say that so far I have been really impressed with what it does.

### ⭐⭐⭐⭐ Working well, so far
*by M***N on 10 February 2021*

Bought this during lockdown to use my Canon EF lenses with an R series camera. Canon UK and every camera shop in UK were out of stock. Even now 10/2 they are predicting a mid march date for the Canon equivalent. So took a gamble and bought this. It is well made, was sell packaged and, so far has worked well. If you have a new Canon R seies camera and want to use your EF lenses, give it a go. So far so good!
