Durst's 35mm enlarging lens — the Neonon 50mm for standard format darkroom printing.
The Durst Neonon 50mm f/2.8 is a 35mm format enlarging lens from Durst's Neonon series, providing a bright f/2.8 aperture for darkroom composition viewing alongside the standard printing apertures at f/5.6 and f/8.
The lens provides 50mm at f/2.8 with Durst's Neonon optical formula for 35mm negative projection, and Durst-standard mounting thread.
The f/2.8 maximum aperture brightens the image during composition and focussing on the easel significantly compared to f/4 or f/5.6 alternatives. Durst Neonon quality is adequate for standard darkroom printing sizes.
Check element clarity. Test aperture ring across all stops. Verify Durst enlarger thread compatibility.
