View lens - for SLR cameras with M42 threaded connection. This lens is installed on modern SLR and mirrorless cameras through the appropriate adapter. Read the article about adapters.

The model itself appeared on the market even before the First World War. But for a century of presence lens on the market, the appearance of the frame has changed many times:

  • Until the thirties, these are mainly large and medium format lenses.
  • In the thirties, they had aluminum shiny bodies, were supplied with Praktiflex cameras, for example, the maximum aperture was f / 3.5
  • In the forties and fifties, the design changed a little, the maximum aperture is both f / 3.5 and f / 2.8, multi-coating. In this form, lenses were produced from 1950 (Exacta, Praktiflex, Praktica FX) to the early 60s, followed by restyling of the body and frame.
  • In the sixties and seventies, they were produced in buildings of the "bicyclic zebra“Like many German lenses of that time
  • In the eighties, the lens has a black body, has multiple variations in the USSR (Industar series)

Body, ergonomics

Earlier variation lens - Carl Zeiss Jena Tessar T M42 50mm f3.5 is visually no different from the hero of the review.

Aperture, focusing

The focus and iris rings are easy to rotate, and the iris ring has a preset mechanism. The front lens is recessed into the housing, the frame protects the front lens from side exposure.

At the open aperture of the Tessar T 50mm f2.8, color aberration is minimal, and the lens becomes very sharp from about f3,2. When installing lens on the digital camera through adapters having a flange for blocking the pusher of the automatic diaphragm pin, the infinity disappears, since the lens does not fully shrink.

The Tessar T 50mm f2.8 features a 14-blade aperture, superior optics and a lightweight aluminum body. "T" in marking lens means anti-glare enlightenment (German - transparenz).

Modern variations with T * enlightenment are relatively expensive on the market. Most modern Zeiss lenses on Canon have manual focus and a built-in focus confirmation chip.

Use on modern cameras

To work on digital cameras, you will need an adapter from the M42x1. Easiest to install on cropped Canon EOS with bayonetohm EF-s, especially considering that adapters without chips on Canon cost mere pennies.

By ordering things from the links below, you help the project cover the costs of site maintenance and development. List of adapters, systems and bayonets (direct links for ordering)

When ordering, it should be borne in mind that cheap adapters of poor quality with a lens on bayonetf Nikon F spoil the picture significantly. Adapters without a lens reduce the maximum focusing range (due to the difference in focal lengths). Adapters with chips come across poor quality, exposure metering and focus confirmation on some Canon EOS models may suffer from this.


Tessar T 50mm f2.8 is a lightweight, high-quality, expensive "fifty-kopeck piece".

  1. As for the fact that “The model itself appeared on the market even before the First World War” is not true. That tessar was soft. The modern post-war Tessar has lanthanum glasses (“Das Neue Tessar”), and comparing it with the pre-war one is the same as comparing Industar-61 with Industar-26.

    1. I have only dug up so far that the schwerkrone was used on some German glasses, it seems, in biotar. About tessars infa did not come across. In any case, I will correct the article as I find confirmation.
