This unit includes:

The Metrogon lens design was originated by Bausch and Lomb during the second world war for aerial reconaissance. They are still treasured for wide-field, ultra-low distortion astrophotography, and are still available on the surplus market. The design (4 elements, symmetrical, with nearly hemispherical elements) has also been copied and produced by other manufacturers in Japan, Germany, and Russia.
