Carl Meyer 100mm f2.3 Type 'A' lens mount_Topcon with a built-in focusing motorA rare lens in a threaded tube, this Carl Meyer 100mm f2. 3 will cover full frame 35mm at infinity, and may cover digital medium format sensors. This lens will require some adapting work to make it mount on a camera: it does not have a camera mount, and will not directly attach to anything, so you'll have to put some work in. Light internal dust, working diaphragm.
