75mm · f/2.3
The Astro Berlin Pan Tachar 75 mm f/2.3 is a rare, pre-war lens originally converted from a cine design. It is uncoated and built with an aluminum barrel, weighing 11 oz, with a closest focus of 1.25m. Optically, it is a Gauss-type design described as a 'super speed high-contrast lens with high color correction'. No specific weaknesses are noted in the excerpts. The lens suits collectors and enthusiasts of vintage, unusual Leica screw-mount optics, though its rarity makes it a mystery even among experts.
