The Sinar F is a 4x5 large format monorail view camera built for studio and field use, offering full movements on a modular rail system. It sits in the entry-to-mid tier of Sinar's monorail range, positioned as a more portable and affordable alternative to the Norma and P-series bodies when new.

At recent UK auction, hammer prices for the Sinar F have ranged from about £94 to £380, with a median around £375, reflecting how much condition and completeness of standards, bellows and rail influence what one sells for. As of 2026, clean outfits with an intact bellows and both front and rear standards tend to sit at the upper end of that range, while stripped or incomplete bodies pull the low end down sharply. Buyers researching what a Sinar F is worth today should note these are wholesale saleroom results rather than dealer retail prices.
