Customer Ratings & Reviews

The product is really good. I would like to thank Best Buy for their helpful guidance and great customer service

I pretty much don’t have to buy the RF lens because I’ve been using the EF for a while and it’s still kicking!

Great adapter, priced ok easy to snap in and use..

ACTIVELY use this on the daily, I own a Canon EOS R10 camera and this allows me to use older lenses. This is perfect.

Good adapter to use ef and ef-s lenses on RF Cameras. Auto focus quick

Works exactly as it should. Allows me to mount all the EF-Glass from my previous Canon camera right onto the R6 without any issues. The only real hitch is if you have any RF glass you'll soon want to upgrade all your EF lenses and scrap the adapter since you won't need it anymore. Simply put...if you have a bunch of EF lenses that you love and plan on holding onto then this adapter is a no brainer if you're upgrading to a mirrorless Canon like I did. If you think you'll be selling off your EF line to upgrade to RF glass then maybe put the $100 you would've spent on the adapter towards a new lens.

this adapter makes using EF glass on RF sensor mounts easy to swap in the field. solid build quality, secure easy lock, and size makes it ideal to either leave on the camera or lens depending what glass you use most. good value, and since i don’t use/need the control ring on the $300 version, id say it’s a better deal. necessary for anyone moving from EF to RF sensors.

Works perfectly . In a good condition as advertised. Flawlesss and made my work easy. Recommended.

This adapter works great on my Canon R6 Mark II. Having recently converted to mirrorless, I had a nice selection of EF mount lenses that I needed to use. This adapter made that possible with the new camera. No issues communicating between camera and lens and auto focus works perfectly. Highly recommend.

This adapter works great with my markii so I can still use my 50mm lens that I bought prior to my mirrorless camera. The images are still great quality!

Works really well. I'm able to take really clear pictures with it.

Good equipment, nice build quality, solid feel, no noticeable wobble. Would recommend getting the control ring version as I already miss having one on my lens.

Very high quality, fast and efficient, works very quickly and well, airtight.

Use the last 30 of canon EF/EF-S lenses on new R cameras. Save money on fancy new lenses if they're too expensive.

Excellent adapter for my Canon camera. Enables me to use multiple older lenses for my new EOS.

Saved me from buying a few lenses! Definitely glad I invested in this!

This lets me use my older lens with the brand new mirrorless camera

This was a great product. I have have had no issues.

Just upgraded to a new Canon R series mirrorleas camera and have a bunch of EF mounts. Good news, you can save money on buying RF mount lens with this adapter. Doesn’t effect the pictures you take one bit.

After ten years my D40 stopped working and needed a new camera. R100 was fitting my budget but then what about my EF fast lenses I had with D40? Well, this adapter solved that problem. It snaps nicely on R100 and then my EF lenses fit nicely on top of this adapter. I am back in the business with all my previous investment in lenses in tact!
