Angenieux 28mm f3.5 Retrofocus Type R11 for Exakta lens mount_Retina which I guess is theThe Angenieux 28mm f3. 5 Retrofocus Type R11 is an uncommon wide angle lens for Exakta mount. In good condition overall, with some paint and finish wear. Aperture moves well, focusing is smooth. Optics are free of haze or fungus, with some cleaning marks (or similar) on internal elements which should not affect the imaging which is quite nice, by the way. Not perfect, but working well. With original box.
