## Questions & Answers

**Q: Is this the speed booster?**
A: No this is just an adapter to enable the use of Canon EF & EF/S mount lenses on a M mount camera like the M50 Mk2.

**Q: will this fit a panasonic g7 camera?**
A: No it will not only Canon Have a look on the Viltrox site they might make an adapter for your camera on there

**Q: Can I use this on a black magic 4k camera. I have 35mm Sanyanang**
A: Blackmagic (cine) cameras are fitted with the Canon EF lens mount, so this adapter will NOT fit your camera, as it's designed to attach to cameras with the Canon EF-M lens mount (which has a smaller throat diameter than EF).

**Q: Would this adapter fit the canon ef 50 mm f/1.8 stm standard prime lens on canon eos m50 camera?**
A: YES,

### ⭐⭐⭐⭐⭐ New life for Canon ef/efs lenses on m mount cameras
*by M***R on 9 December 2025*

Works perfectly on my Canon M50 mk2 and M100 cameras, enabling use of ef/efs lenses bought in previous years. No change in focus speed or accuracy compared to M lenses. Well made and great value for money.

### ⭐⭐⭐⭐⭐ Works well
*by M***M on 4 January 2026*

I use on a Canon M50 camera to mount canon EF lenses such as lens baby lenses. Good fit, autofocus works well, no noticeable noise. Would recommend

### ⭐⭐⭐⭐⭐ A simple device with enormous potential
*by K***R on 19 July 2025*

OK I was extremly sceptical about this item but I'm now a true convert. I had recently purchased a canon EOS M50 compact but missed my old ef-s lenses from my old canon 350 slr. My old canon digital slr, although working is considerably dated and time moves on. So how does one marry the superb ef-s lenses with the new mirror less all singing and dancing EOS M50. You purchase a lens converter. Low and behold to my utter disbelief it actually works. Both manual and automatic focus are available through the contacts on the device. Fantastic, as I now have high quality optics married to a new high tech camera. Thoroughly recommend the device as it is well made and a perfect addition to my camera. At under forty quid it has saved me paying out a fortune for new lenses. I look forward to trying out all my lenses using the device. I'm also impressed with the additional mounting which I can attach a mini tripod to stabilise my 100 to 300 zoom. The device is extremely light but well built and hardly adds any weight to the camera. Have the robust ef-s lens on the camera also makes it feel like my old slr. All very well thought out.
