Second lens of the MS Optical Historical Series Collection: In 1905, Dagor was released by Design Gelts Company by von Hoof. Although it is a dark lens, its high performance far exceeded triplet and Tessar types, for studio use, scenery etc. A high evaluation was given for drawing. Glass at that time was discontinued one after another, luck was available and restoration design was possible. MS Optics think that this lens will be the last lens since two types of glass materials used will be lost soon. The resolving power and the contrast are 10 to 15% higher than the previous prototor, 10 [mu] or less when opened, and 5 to 8 [mu] images at f8 or more. The color of "raw" is beautiful with transmittance of 98.5% by multicoat on all 4 reflective surfaces of 2 groups 6. Distortion aberration is + 0.13% It is recommended to use for high-quality macro shooting with very little degradation of aberration due to distance. The difference in color number is corrected to be comparable to that of apolens, and it is also the reason that a sharp, cutting good image with little blurring in both color and nochrome can be obtained. Initial lot of lenses, designed, manufactured and hand-assembled in Japan by Mr Sadayasu Miyazaki.
