Carl
Zeiss Jena Biotar 58mm f/2 lens has a long genealogy. 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.
