EOS to NEX Adapter, K&F Concept Lens Mount Adapter Compatible with Canon EF S and Sony E Camera Body

Manual adapter, no electrical contacts in the adapter ring and cannot achieve auto diaphragm or auto-focus, pleAse be careful. This adapter helps to connect EOS EF mount lens to NEX E-mount mirrorless cameras. As EOS lenses are electronically controlled, most EOS/EF mount lenses do not feature a manual aperture ring, so when used on our EOS lens side adapter, which is a full manual adapter ring, the aperture could not be transferred to the camera, it will stop down to its smallest f/stop by default. Infinity focus function is allowed, please adjust manually when first use. Upgrade all-metal design and anodized aluminum construction. Any question about products please contact us freely.
