It was developed by the famous lens designer Dr. Willy Walter Merté for Carl Zeiss, shortly after these earlier lenses, and all three lenses used a similar formula; they were six element lenses with asymmetrical outer elements, a variant of the Double Gauss design for higher performance and increased field correction and speed. The manual Biotar 58mm model is the smallest and most well-made of all the different models, and it closely resembles the pre-war lens in design and construction. It was first manufactured from pre-war brass parts with a hard chrome or nickel plating, and later in aluminum. It also came in a rare black lacquer coating with white markings, which is the most collectible. In this lens, Zeiss’ optical coating became a standard option for the first time. This was also the first model offered in M42 mount, but the vast majority of lenses were manufactured in Exakta mount. A post-war lens was produced in M40 (Praktiflex) Mount, but it looks almost identical to the pre-war version. Beware that this version of the lens was produced just after WWII, and it’s very common to see small bubbles in the glass which result from production processes. This is not a fault, and unless they are unusually large does not affect image quality. The bokeh of the Carl Zeiss Jena Biotar 58mm f 2 has a characteristic twirling with the aperture wide open. In general, the lens renders very flexible, and, at the same time, sharp image. Back, side and scattered light is not well handled, the use of a hood is recommended. There are chromatic aberrations discernible in contrast images. The variants with multi-blade iris and instant-return apertures were produced. The aperture had the different number of blades: 17,12,10, 8. The Carl Zeiss Jena Biotar 58 mm f/ 2 is fit as an everyday kit lens. It is not bad as a portrait lens as well as an effects lens. ************************************************************************************************************************************************************************************************************
