I bought 3 of these and sold it all for profit. I have a discount code every time I purchase this here so even more profit for me. Also, thanks Canon for being sold out and hard to find.
I would recommend this to a friend!

This works really well on my eos r with sigma 150-600, not to mention all my other EF and EF-S lenses.
I would recommend this to a friend!

Works as Intended

You can use your EF mount lenses on Canon RF mount Cameras.
Canon should actually provide it free like they did with Canon R and Canon RP cameras.
But it is what it is. $170 Canadian dollars and it works as intended, with pretty fast and accurate focus on the EF lenses
