I camera model I've made to teach myself Blender. The model is based on Leica M3 camera with a 50mm lens. There are no markings on the lens or the camera (aperture scale, model number etc.) and focus ring's shape is a bit off from the original. In all other regards I tried to stay true to the prototype. UV coordinates are a mess, I'm surprised they worked at all.
Aperture ring is really weird, but it's well hidden.
