Lens adapters expand the functionality of your DSLR and mirrorless cameras, opening up a wide range of lens choices and options. They also save you a ton of money! Rather than re-purchase new lenses, you can use what you already have. When it comes to choosing a lens adapter, you want one that has precise craftsmanship so it goes on easily yet fits perfectly so you experience no ill effects to image quality, like light leakage. Novoflex adapters meet and exceed these standards. This adapter gives your Canon EOS DSLR camera the ability to utilize the entire range of Nikon lenses. NOTE - This adapter will not transfer camera functions to the lens (ex. Autofocus & Automatic Diaphragm/AE Metering). You will need to manually set the aperture (stop-down the lens) since it will not be controlled by the camera body.1-Year Manufacturer's Warranty.
