The Schneider-Kreuznach 240mm f/9 G-Claron is a large-format process lens, originally designed for graphic arts reproduction and copy work at high magnifications. Its compact barrel and modest f/9 maximum aperture made it popular among large-format photographers seeking a lightweight long-focal-length option, typically mounted in a shutter for field use on 5x4, 5x7 and 8x10 cameras.

UK auction activity for the 240mm f/9 G-Claron is thin, with the most recent hammer result we have on file from November 2025 selling for £60 at saleroom level — a wholesale figure that excludes buyer's and seller's commission. With only a single data point in our records as of 2026, that price should be treated as indicative rather than a firm market value, and clean examples mounted in a working Copal or Compur shutter typically sell for considerably more than a bare barrel-mount copy.
