Minolta UW Rokkor PG Ultrawide 18mm f/9.5
Super wide pan-focus lens to fit Minolta manual focus cameras. Very small and light weight lens.
Comes with a case, metal lens shade, yellow filter, UV filter (filters are mounted to the rear of the lens), and a spanner key to attach the filters.
We tested the lens on a Sony A7R4 full-frame camera (see the last two photos) and got exceptional results.
There is a name and ID number etched to the side (see photo; I blocked most of it for security purposes).
