Extension tube set for Sony E/FE for macro photography

thingiverse

This set of extension tubes enables macro photography using your existing Sony E/FE lenses on your Sony E/FE mirrorless camera. I've provided tubes in 7mm, 12mm, 24mm and 35mm lengths Since there are no electrical contacts, you won't be able to control the lens' aperture from the camera. Ideally you would use a third-party lens that has a manual aperture ring (which works even without power). Otherwise you can mount your lens directly to your camera, set your camera to A (aperture-priority) mode at your desired aperture, and then remove the lens while the camera is still powered on. This will cause the lens' aperture to say at your desired position even after the lens is removed from the camera. As a very general rule of thumb, you can figure out how much magnification will be added to your lens' max magnification by dividing the length of extension by your lens' focal length. e.g. if you add a 24mm tube to a 50mm lens, you can expect to add 24/50 = 0.48x to your lens' max magnification (so for a typical 50mm lens with 0.25x max mag, you can expect around 0.75x magnification afterwards). The example photo above is my jeans with 7+12+24+35mm extension tubes added to my 85mm Laowa 2x macro lens.
