H Dallmeyer, London, 2D Patent, "unscrew for soft focus". Dallmeyer London N°1 Compound Tele Attachment, Patent 1891. A very beautiful set, Dallmeyer 2D is a soft focus lens, sought after for unique rendering in portraiture photography. This is the late version of 2D, with the "unscrew for soft focus" system, much easier than the early versions. You can turn the back of the lens and put in front of one of the 4 different notches of the barrel.
Also included a genuine Dallmeyer Tele Attachment n°1. The original mounting flange is mounted on a extended wooden lensboard (82x82mm), and you can fit the lens with or without Tele Attachment. Brass 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. Total length: 86mm (lens alone) / 120mm (+ tele attachment) / 188mm (+ lens board). Diameter at mounting thread: 50mm. Size of lensboard: 82x82mm and 65mm of extension. A very nice and rare optical tool, for artistic photographers, wet plate enthusiasts, and hobbyst ready to use this lens on digital cameras.
