H Dallmeyer, London, 2D Patent 1866 & 1909, "turn for soft focus" n°100xxx. A very beautiful lens, Dallmeyer 2D is a soft focus lens, sought after for unique rendering in portraiture photography.This is the late version of 2D, with the "turn for soft focus" system, but the system is frozen and needs attention. Of course, you can use this lens as portrait lens as is without soft focus rendering. The mounting flange is included (I can't unscrew it, and is hand engraved "trousse grosse monture et eurygraphe"). Black barrel wears some signs of the years and is in good condition. Glasses are bright and complete, with slight cleaning marks and tiny dust. The iris turns as it should and is graduated from 6 to 32. Original front leather cap is included. Diameter at mounting thread: 50mm. A very nice and rare optical tool, for artistic photographers, wet plate enthusiasts, and hobbyst ready to use this lens on digital cameras.
