You'd probably be happier with the $250-$300 active extensions, which allow focus and aperture changes with it attached. (this cheap metal tube does not) **Q: What will happen to the picture quality if the "inner glass" is removed? Also, whats the difference between this one and the other ones on the market??** A: After much testing with Canon FD 300mm prime and Tamron 500 reflex. 2 inner lenses destroys the sharpness. Removing both you lose infinity on Canon but not reflex lenses. Keep the thick inner lens remove the thin one. Perfect. Except now MFD is a little greater. Not important. Sharpness! Remove both for all common reflex lenses still keep infinity. **Q: Does this mount directly to the body? I have a macro lens that I just bought but it is one the screws on to an adapter. Will this work?** A: It doesn't fit directly onto the body of the Canon EOS M. YOu will need the mount adapter EF EOS M. I bought this with the 0.43x wide angle macro lens 58mm that screws onto the front of my lens. It dose not fit the wide angle macro lens that I bought with it. The wide angle macro lens fits onto the front of my Canon EFS 55-250mm lens. I bought it so I would have the option since it is cheap enough and it gives different results. But since it is manual and it doesn't communicate with my camera, the EOS M sends out a message that a lens is not attached to the camera. However, if you can get it to work with your camera, you can get real close with your zoom lens. **Q: Will this extension fit on my Canon Rebel t3i?** A: Miss: Alyssa C. My one and only experience has been with the Canon Rebel T3. However, on 30Jan2014 I bought a wide angle lens for my T3. The lens was for a T3i. It fitted just right. It works great in photography involving flowers. ## Frequently Bought Together - Fotodiox Lens Mount Adapter - Compatible with Black M42 (42mm x1 Thread Mount) Lens to Canon EOS (EF, EF-S) Mount D/SLR Cameras - (5 Packs) Rear Lens Cover Cap for EOS EF Lens, Ef-s Lense Dust Protective Rear Cover, EF Lens Cap, Compatible with Canon EF EFS Mount DSLR Lenses - Fotasy Copper M42 Lens to Cannon EF Adapter, 42mm Screw Mount Lens to EFs, Infinity Focus, Compatible with Canon DSLR 6D 5D Mark IV III II 1Ds 1D 7D II 90D 80D 77D 70D 60D 50D 1300D 1200D 1100D 760D --- ## 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.th/products/271348717-fotodiox-m42-to-canon-eos-ef-ef-s-adapter-all](https://www.desertcart.co.th/products/271348717-fotodiox-m42-to-canon-eos-ef-ef-s-adapter-all) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-12*
