Schneider-Kreuznach G-Claron · 355mm f/9

{"overview":"The Schneider-Kreuznach 355mm f\/9 G-Claron is a large format process lens from the German optical maker, originally designed for high-resolution flat-field reproduction work such as copying and graphic arts. Its modest f\/9 maximum aperture, long focal length and generous coverage also made it a popular choice among 8x10 and ultra-large-format field photographers who repurposed process lenses for landscape use. It is typically supplied in a barrel or Copal shutter and covers well beyond 8x10 at working apertures.","market_narrative":"At recent UK auction, hammer prices for the 355mm f\/9 G-Claron have ranged from £130 to £375, giving a midpoint around £250 based on the limited sample available in 2026. Clean, shuttered examples tend to sell for more than barrel-only copies, which helps explain the spread between these two saleroom results. Because the data set is small, individual condition and whether the lens is mounted in a working Copal shutter have an outsized effect on what a given copy is worth.","buying_guide":"Inspect the glass carefully for fungus, haze and cleaning marks, as process lenses have often spent decades in studio or darkroom environments. Check the aperture blades for oil and sluggish movement, and if the lens is in a Copal shutter confirm that all speeds fire and the self-cocking mechanism is smooth. Also look for signs of element separation at the cemented groups, and verify that the mounting threads and retaining rings are intact, since barrel-mounted copies are frequently re-shuttered by previous owners.","specs":"The lens is a 355mm focal length with a maximum aperture of f\/9, made by Schneider-Kreuznach under the G-Claron process lens line.","faq":[{"q":"How much does a Schneider 355mm f\/9 G-Claron sell for at UK auction?","a":"Recorded UK hammer results sit between £130 and £375, with the price a given copy fetches depending mainly on shutter condition and glass clarity."},{"q":"What is a 355mm G-Claron worth today?","a":"Based on the current sales data, a typical value in 2026 falls in the £130–£375 range at auction, with shuttered examples in clean optical condition sitting toward the upper end."},{"q":"Is the G-Claron suitable for 8x10 photography?","a":"Yes — although designed as a process lens for flat copy work, the 355mm G-Claron is widely used on 8x10 and larger formats because it delivers ample image circle at typical working apertures."},{"q":"Why do prices vary so much between copies?","a":"The main drivers are whether the lens is in a working Copal shutter or bare barrel, the state of the coatings, and the absence of fungus, haze or separation."}],"confidence":45,"reasoning":"Only two sales records are provided and SPECS\/variants\/facts are empty, so pricing and technical detail are necessarily limited to what can be inferred from the model designation and the two hammer prices."}
