Used: Spiratone Auxiliary wide angle lens set for size bay 1 Rolleiflex and Yashica mat cameras
This is a Japanese made set of auxiliary lenses that fit bay 1 TLR's and give it a wider angle of view. How wide? I'm actually not sure. I'm hoping someone will let me know! I've never used one. The kit is in very nice condition with the glass on both viewing and taking optics in excellent condition. Comes with zipper case and cap for front of the larger lens.
