This is a Rapid Weitwinkel Orthar 7.3cm F6.8 wide-angle interchangeable lens for the Plaubel Makina II S 6.5 x 9cm (large business card) camera. The Makina series, with its behind-the-lens shutter, is a precursor to the Makina 67 and follows the lineage of the original Makina. This lens is a wide-angle interchangeable lens for the series, featuring all-group rotation and has been converted to an EOS mount. As it is approximately 90 years old, there is some deterioration due to aging, but the optics have few scratches. However, as it is a non-coated lens, flare will occur in backlit situations. (Original front and rear caps are included.) How about it for those who want to enjoy shooting with a vintage lens from the 1930s? Thank you for your consideration.
