Review: Not tested yet on an eos m yet as still waiting for it to be delivered however all my ef Efs lenses fit on it great value compared to canon's ef to eos m adaptor which is massively over priced great little adaptor on a side note though if you have the money I would recommend get the viltrox ef to eos m2 as that has wide angle glass built in which is supposed to really boost the light intake when using ef lenses from what I know the m2 version doesn't support efs lenses that's the only drawback of the m2 I don't actually have an m2 adaptor yet and didn't have the cash to buy one as I spent it on an eos m camera so I can run magic lantern an unofficial semi custom firmware upgrade which will give me stable 10,000 frames of 2.5k raw video format video and about one minute of 4k animorphic 4k recording time I also intend to attempt to port magic lantern to the as yet unsupported canon 2000D that a very kind man donated to me brand new if I hadn't been looking for hacks for that camera I would never have stumbled on magic lantern firmware upgrade and would never have bought an eos m camera thanks to this adaptor and the fact I was quite lucky and got the eos m for £125 with an 18-55mm mirrorless kit lens I will be able to use my ef and efs lenses along side the one mirrorless lens that I now own again though if it's just ef lenses I are using if you have the cash I would seriously consider spending that bit extra for the m2 version however this is still needed if you like most people have a mixture of ef and efs lenses p.s if you are skilled with you canon mirrorless camera and it is one of the models that supports magic lantern I would seriously consider checking it out for me as a new camera user but with specific specialist requirements for a camera such as 360 panoramic hdri environment maps for use in 3d scene lighting and photogrammetry and videogrametry I'll be sticking with canon a viltrox speedbooster is a must buy for any mirrorless camera user who also has other lens types recommended to any eos m users just to broaden you lens range granted I can see this version maybe causing some light loss to the sensor due to it being an extender addon meaning the lens is further away from the sensor but that's a trade of you have to make if you want to be able to use various lens types that are compatible with the ef and efs range or other brand with whatever fitting to ef adaptor (will try this out but wouldn't reccomend d as it will push the lens even further away from the sensor overall a great little affordable and practical purchase for a budding semi pro/am specialist photographer and videographer

## Questions & Answers

**Q: Does it work for Cannon EF 75-300 mm lens?**
A: Yes it does. I use that lens very often with my M 50...works perfectly.

**Q: I bought this adapter to go with my canon eos rp camera and canon ef-s lens. is this the wrong adapter? I cant get the lens to mount to adapter.**
A: Hello,
The latest EF-EOS R can work with EF lens as well as EF-S lens, but the old verson doesn't. Our guy make some mistake and send the old verson of EF-EOS R to amazon warehouse. That is why it does't work with EF-S. We just found this mistake and amended the description on the website.
We apologize for this. Please return the adapter to amazon and they will give your refund. Sorry again.

**Q: Does it work with the canon ef 2.0x iii telephoto extender?**
A: yes

**Q: Does these mounts crop the image? I dont want to lose the full frame**
A: As long as your camera's sensor is full frame, you do not have to worry about the adapter cropping your photos. I own the Canon EOS RP and the adapter works wonderfully with my EF lenses.
