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!! ## Customer Reviews ### ⭐⭐⭐⭐⭐ IT WORKS! FOR CANON EOS M50 CAMERA *by M***S on May 12, 2026* SO, Canon has a lot of different lens! This adapter is for A Canon EF to EF - M lens! It works! I just got a Canon EOS M50 CAMERA! IT FINELY WORKS! ### ⭐⭐⭐⭐⭐ Game Changer!!! *by D***N on August 15, 2025* Brought a better life back to my M50, quality and functionality are great, should have bought one of these sooner! ### ⭐⭐⭐⭐⭐ Great for longevity *by A***R on April 2, 2026* Love using this, bought it for my Canon Eos M50, had an old EF lens lying around and decided I wanted to try it on my M50. Autofocus works and ever since then I've bought many more EF and EFS lenses. The build I'd say is surprisingly durable and its quite secure, so far there has been no wiggle in every lens I've used with it. I love that its compatible with EF/EF-S lenses, but I guess that's a given haha. Definitely get an adapter like this if you're in the EOS-M mount and don't want to upgrade for awhile. ## Frequently Bought Together - VILTROX EF-EOS M Lens Mount Auto Focus Adapter, Compatible with Canon EF/EF-S Lens to Canon EOS M (EF-M Mount) Mirrorless Camera Body EOS M100 M50 M3 M10 M6 M5 - Canon EF 50mm f/1.8 STM Lens - Canon EF 75-300mm f/4-5.6 III Telephoto Zoom Lens for Canon SLR Cameras --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/42376591-viltrox-ef-eos-m-lens-mount-auto-focus-adapter-compatible](https://www.desertcart.co.uk/products/42376591-viltrox-ef-eos-m-lens-mount-auto-focus-adapter-compatible) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-21*
