Durst's mid-tier enlarging lens — the Neotaron 50mm f/2.8 for 35mm printing.
The Durst Neotaron 50mm f/2.8 is a mid-tier darkroom enlarging lens from Italian manufacturer Durst. Positioned between the basic Neotar and the standard Neonon in Durst's hierarchy. The f/2.8 provides a brighter focusing image than slower alternatives. At 50mm, it serves standard 35mm negative enlarging in Durst enlarger systems.
Mid-tier Durst quality — between the basic Neotar and standard Neonon. The f/2.8 provides brighter focusing than f/3.5 alternatives — a practical darkroom advantage. Flat-field correction adequate for standard darkroom printing from 35mm negatives. Not a camera lens — designed exclusively for projecting negatives onto photographic paper in an enlarger.
No camera mount — enlarger thread for Durst and compatible enlarger systems. Weight minimal as a small optical assembly. Build quality functional Italian manufacture from Durst. The f/2.8 brightness is the main practical advantage over the cheaper Neotar tier within the Durst enlarging lens range for 35mm format work.
Essentially free on the used market given declining darkroom demand worldwide. The f/2.8 brightness is the sole advantage over cheaper alternatives. Not a camera lens and cannot be practically used for photography. Better enlarging lenses from Nikon EL-Nikkor and Rodenstock Rodagon available at similar near-zero pricing.
