## Questions & Answers

**Q: Does this adapter work with canon ef-s lenses? some people say it does and other say it doesn’t.**
A: Hey! I have the 10-18mm EF-S lens and it will not mount on this because of the glass element. BUT - if you physically remove the rubber that protrudes it may fit. I saw someone do that on youtube but you can see the inner barrel of the ens at 10-12mm which to me defeats the purpose of it.

I believe the main thing that prevents EF-S from mounting is that rubber that protrudes into the sensor.

**Q: Can it adapt Nikon lens to mirrorless cam aswell?**
A: Viltrox adapter is designed for Canon M50 camera   as far as I know.

**Q: Will it work with sigma 18-35?**
A: No. The Sigma 18-35 Art is an EF-s lens will not work with this adapter and the EOS-M body. EFS lenses will vignette with a visible circle in the corners.

**Q: Is this better than canon’s adaptor?**
A: Hello,
I haven't tried the Canon version, but the Viltrox (EF lens only) is a speed booster. Canon adaptor vs Fotodiox EF/EFS adapter is a better comparison. 
The Viltrox allows you to open the f-stop by 1 stop & reduce the 1.6 crop factor (example a 50mm f1.8  NOW resemble a 56.8mm f1.2).
The auto focus is 9/10!! Imagine quality is great but there is a glass element in the center of the Viltrox but image quality is still awesome.  I love the Viltrox!!
