The Rodenstock 90mm f/6.8 Grandagon-N is a wide-angle large-format lens in Copal shutter, covering 4x5 with room for movements. It was designed for architectural, landscape, and studio work on view cameras where generous image circle and corrected wide coverage are required.

At recent UK auction, clean examples of the 90mm f/6.8 Grandagon-N have sold in a range of £230 to £320 at the hammer, giving a midpoint around £275 based on the two 2025 results on file. These are wholesale saleroom figures rather than dealer retail, so what a copy is worth to a private buyer today in 2026 typically sits a little above that band once commission and condition premiums are factored in.
