Rodenstock Grandagon · 90mm f/6.8 N

{"overview":"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.","market_narrative":"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.","buying_guide":"Inspect the front and rear groups under a torch for fungus, haze, and cleaning marks, as wide-angle elements on view-camera lenses often show edge haze after decades of storage. Check the Copal shutter fires accurately at all speeds, confirm the aperture blades are dry and snappy with no oil migration, and look for separation or coating scratches around the large rear element; smooth, even aperture action and a clean, unmarked barrel materially affect price.","specs":"Key specifications from the supplied data: a 90mm focal length at maximum aperture f\/6.8, sold as the Grandagon-N variant intended for large-format view cameras.","faq":[{"q":"What is a Rodenstock 90mm f\/6.8 Grandagon-N worth today?","a":"On the UK auction evidence available, it is worth roughly £230 to £320 at the hammer, with clean, fully working copies in Copal shutter sitting toward the upper end of that range."},{"q":"How much does a 90mm f\/6.8 Grandagon-N sell for at auction?","a":"Recent UK saleroom results show a price of £230 in May 2025 and £320 in November 2025, so typical hammer values sell for a mid-£200s to low-£300s figure."},{"q":"Is the Grandagon-N 90mm f\/6.8 a good value wide-angle for 4x5?","a":"Yes — at current price levels it remains one of the more accessible wide-angle options for 4x5 view cameras, provided the shutter and glass are clean."}],"confidence":45,"reasoning":"Only two unverified sales records and no SPECS or variant data were provided, so pricing is indicative and technical detail is limited to widely-known category information."}
