This is a compact lens, when related to the focal length. With a production life of only four years, it was made in larger quantities and so is relatively easy to find.

There is a visible change in style and choice of focal lengths in the SLR system, where more and more users preferred the 180 to the 135, because of the higher magnification. Yet, the 135mm has a very fine perspective for many subjects, not the least for portraits.

The first version of this lens appeared in 1963 for the M-system. A year later the version for the R-system was put on the market. This version had almost the same lens prescription as the first version: only the two separate front lenses had less thickness and different glasses were used. Performance–wise there is hardly a difference. This second design has been used for both the M- and the R-systems, but it is not exactly clear when the merger took place. The same story does repeat itself with the last redesign, which first was introduced for the R-version and later incorporated into the M-system. Wider aperture versions (1:2) have been researched for the R-system and offered good performance, but the days of the 135mm lens were numbered. Once a classic focal length for 35mm photography, the 180mm lens and the vario-lens (70-210 mm) became the standard for long-focus picture taking.

The Elmarit (I) is a good performer with the low contrast characteristic of a high-speed tele-lens of the first generations. Stopped down contrast and definition improve to a level that can be used with fine grained low speed film emulsions.
