I went for this one for my new Canon EOS RP since Canon's own is sold out. Works well. Works as it should.

Not much to say here, this device allows you to mount an EF lens onto your EOS-M camera, and appears to be well built. Done.

Attached the clip to my backpack strap and carried my EOS RP no problem. First time out we went on a 8.5 mile hike with 2,300 ft elevation and never had 1 problem. Not sure what other ppl are talking about “losing a screw” it comes with 2 sets to attach to your backpack strap if you don’t think you can get it tight enough. The second set is an Allen head type screw. It even included an Allen wrench. I just tightened by hand and had no issues. I will continue to use this product with confidence.

I have a Canon EF to EOS R adapter for an EOS RP camera and I bought this adapter to reduce the swapping. From what I can see it works as well as the Canon one. I tested it on a 17-40 F4L and on a Sigma 100-400 5-6.3 C and I saw no difference. So I'm very happy with it.

So I purchased this to use with my Canon EOS RP and it worked perfectly. It was sturdy enough to handle some windy conditions and I was confident that it would hold my expensive camera. Has 3 different levels so I was able to get all the shots that I wanted. I recommend this!

I got this lens to be a lightweight "walkaround" prime for my EOS RP.It was small and light, especially compared to the RF 24-105, but that's about the only good thing I can say. Build quality, focusing speed, and focusing noise (for stills) was just so-so. I returned it after a couple of weeks. I guess what I really wanted was an RF pancake lens, like the 40mm STM. Of course, YMMVP.S. I totally don't get the point of a 35mm macro lens on a full-frame camera. A close focusing 35mm, yes. But, bugs and flowers?? Furthermore, the EF version of this lens has a handy little ring light built in. Why take that away?

Works great on my EOS RP but it is a little tighter to turn than just a lens.

I was looking for a lens for my Canon EOS RP that's compact enough to carry to theme parks. I think this is it. A telephoto lens would give more shooting options, but I think 35mm provides portability and a good compromise in focal length for a day out in the park, where you can't carry too many bulky things. This is good for both photography and videos. The image quality and the stabilization are both great. There are so many more detailed and technical reviews on Youtube; find them if you're interested. This is a vote for the product in terms of portability, quality, price point. Recommend.
