About the product.

The Yashica 635 is the most interesting twin-lens reflex Yashica ever built. Produced from 1958 to 1971, it is a conventional 6x6 TLR with one unusual trick: with the optional factory adapter kit it also shoots 35mm film, making it the only mainstream TLR designed from the outset for both formats. You look down into the waist-level finder at a big bright square, crank the film on, and get twelve 6x6 negatives per roll of 120 — nearly four times the area of a 35mm frame.

In short

This is about as clean as a 635 comes — every shutter speed working, clear glass, and the original case and strap still with it. The minimal dust in the viewing prism is normal for the age and does not reach the film. The 35mm adapter kit is not included, so this shoots 120 only.
