Must have if you are transitioning from dslr to RF system. I’d skip the gimmicky control ring adapter and get this plain Jane one for 100 bucks. Every lens I’ve adapted has worked seamlessly and autofocus is super snappy.

Great adaptor, did what i needed it to. I had a bunch of old lenses and so this helped alot.

This is PERFECT for my older lenses. I did not have to buy the rediculous priced RF lenses and my old lenses work even better with this adaprot and the R8

Works great! Thanks for the awesome service! This adapter was a seamless transition from one lens to my others and fit camera perfect!

Perfect for using non RF lenses on a mirror less from Canon. Works seamlessly and is perfectly compatible. I’m currusing this mount to connect my non RF prime lens 50mm to my R8 and the results are great.

Just as described so you can use your older equipment

I just transitioned from the Canon M5 mirrorless to the Canon RP, so this works great with the lenses I currently own. No need to purchase any new R lenses.

Very high quality converter. I am so glad I found this item as now I no longer have to invest over a $2,000 In a new mirroless lens. 10/10

Was exactly what i was looking for to be able to use old EF lenses on the new R6 mark II with the new RF style lense adapter

Exactly what we needed. High quality lens adapter that works exactly as intended

I returned this only because I found the one that was lost… someone found it and turned it into the venues lost and found. But I use this adapter for the EF 135mm that isn’t on RF yet. I’ve tried other 3rd party brands and it’s not worth it.

Works as advertised and allows you to use your old lenses!

I love this adapter I can use all my lenses on my new rp camera and it’s the best thing I ever bought!!!

One of the best purchases I have ever made. I use this product with my camera

Adapter works way better then expected. Thought it would be a horrible experience like adapters are with sony mirrorless. However this adapter makes canon ef glass focus just as fast as native rf lenses do from the lenses I've tested. This also makes ef lenses focus faster on the rp then canons DSLR in my experience. Highly recommend this adapter.

Fit perfect and easy to use so i am able to use all my cannon lenses

I had to buy this mount to be able to use my collection of EF lenses when I bought the R5. Compared to the RF counterpart lens that I have tried and experimented, personally the EF+mount combination is not as good in many fronts. Having made the switch to mirrorless, I don't think I would ever go back to DSLR, so eventually I would be looking into slowly replacing into RF lenses. For anyone who is deeply invested in EF lenses like myself, this is of course a quick and cheap solution for the mirrorless transition, but if not, I would consider purchasing RF lenses even though they are almost twice as expensive as their EF counterparts.

Works great with EF lens, allows all functions of my older lens on my new canon R8 work without issue. Worth the purchase.

This is a great product, and the shipping is always great as well!

These are in short supply at least in early 2021. Make sure you have a reliable line on one if you expect to use your R-mount camera with older lenses, otherwise you'll be like me with a very expensive brick waiting for the adapter to arrive so you can start taking pictures! I paid for expedited shipping and Best Buy waited 2 weeks to ship it anyway. But that's a comment on Best Buy and not the item. The adapter is sturdy- I've been using it with a 150-600mm lens and no droop or light leaks. The only reason I give it "Average" value is because there are no optics in it, it is just a spacer for the EF lenses with electrical pass-through and no particular weather sealing. But once you drop $2k on a camera I guess canon figures you won't blink at $100 for an adapter like this.
