Schneider's large format process lens — the G-Claron 210mm for macro and repro photography.
The Schneider G-Claron 210mm f/9 is a process/repro lens from Schneider-Kreuznach designed for flat-field reproduction, copy work, and macro photography at moderate to high magnification. The G-Claron series is optimised for close-range flat-field work rather than infinity focus. The slow f/9 aperture ensures maximum DOF for repro work.
Optical performance is optimised for close range — outstanding flat-field correction for document reproduction, artwork copying, and scientific macro work. The f/9 is deliberately slow — maximising DOF and correction. At infinity, performance is adequate but not the design intent. Schneider's German precision ensures consistent quality.
Large format mount — typically in a Copal shutter for 4x5 or 8x10 cameras. Can also be barrel-mounted. Weight varies. Build quality is excellent German precision. The G-Claron is a process lens — designed for specific close-range work rather than general photography. Adapts to digital scanning and macro setups.
Available at low prices — process lens demand has declined. Check clean optics. The G-Claron is respected for repro and macro work. Can be adapted to digital cameras for high-quality macro and repro. The Schneider quality is genuine. Best for photographers who need flat-field macro precision.
