Build Your Own 30mm Adapter for Canon EF lenses - 3D Printed

Build Your Own 30mm Adapter for Canon EF lenses - 3D Printe

You may have already heard the buzz about professional lens adapters, such as this one. An adapter increases the amount of light that reaches the sensor by adding an additional glass element between your camera and flexible EF-mount lens. This can be especially useful if you're shooting with older manual focus lenses that don't have electronic contacts or aperture rings, or if you want to use a particular lens on a full frame camera without cropping it

This 3D printed adapter is designed to fit onto any Canon EF-mount lens with a diameter of 30mm or less, including those from manufacturers like Canon, Nikon and Sigma. It includes a 20mm extension ring as well as a set screw to secure it in place. The entire assembly is made from high quality materials and should last for years to come.
