Review: Great alternative to the original Canon adapter - I bought this adapter simply because the original Canon adapter is out of stock from all the places (no idea why is that, I searched over 2 months for the original Canon adapter without success). The adapter works great, the quality feels good and I have no complains at all. Review: Works with ALL my lenses on my Cannon R6 - Initially I wanted the official canon adapter, however these were out of stock with no date for restocking so I bought this instead. Although I can’t compare this generic item to the branded Canon adapter, I have to say that so far I have been really impressed with what it does. All my EF lenses (Canon 100-400l mk2, Canon 100 macro, Sigma 150-600, Sigma 150 macro) work perfectly with all functions operating as I would expect. At at least half the price of the Canon adapter, I have no hesitation in recommending this item. ## Features - 【Compatibility】Allow Canon EF/EF-S Lens to Canon RF Cameras .Please refer to the compatibility table before you purchase our CM-EF-EOS R lens adapter.

Canon UK and every camera shop in UK were out of stock. Even now 10/2 they are predicting a mid march date for the Canon equivalent. So took a gamble and bought this. It is well made, was sell packaged and, so far has worked well. If you have a new Canon R seies camera and want to use your EF lenses, give it a go. So far so good! ## Frequently Bought Together - Commlite CM-EF-EOS R Lens Adapter, Electronic Auto-Focus EF to R Mount Adapter for Canon EF/EF-S Lens to EOS R, EOS RP, EOS R6, EOS R5 Series Mirrorless Cameras - SanDisk 128GB Extreme PRO SDXC UHS-I Memory Card - C10, U3, V30, 4K UHD, SD Card - SDSDXXD-128G-GN4IN - Artman LP-E17 Battery 2-Pack and Rapid Dual USB Charger for Canon EOS R100 R50 RP R10 R8, Rebel T8i, T7i, T6i, T6s, SL2 SL3, EOS M3, M5, M6, EOS 77D 200D 250D 750D 760D 800D 8000D Digital SLR Camera --- ## 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.sg/products/106682823-commlite-cm-ef-eos-r-electronic-auto-focus-lens-mount](https://www.desertcart.sg/products/106682823-commlite-cm-ef-eos-r-electronic-auto-focus-lens-mount) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-05-07*
