Carl Zeiss Tessar 50mm F2.8

It is a very light and compact lens with a very simple construction, it has a minimum focusing distance of only 35 cm, that allows it to be a good lens to use in macro images.

When there is little lighting there are problems to take pictures in maximum aperture f / 2.8

The Zeiss Jena lenses were made in four basic finishes:

1. The first has all the shiny aluminum, often with a leather band grip on the focus ring. These were made from approximately 1956 to 1963, and all were of a single coating.
2. The second one was black with a hard plastic focus ring that has raised ovals, made from '61 to '63, and with simple coating.
3. The third type is called "Zebra" and was manufactured between 1963 and 1967 in large quantities. They are black with alternating bands of shiny aluminum on the control rings.
4. The fourth type is all black, either painted or anodized. They were made from 1967 to 1978 with unique coatings, and from 1978 to around 1990 with multiple coatings.
