Carl Zeiss Jena Universal finder 436/1 for pre-war Contax I black/Chrome 5cm - 18cm , in very fine full working condition.
The Zeiss Jena 436/1 is a classic, multi-focal-length optical viewfinder made by Carl Zeiss in Jena. It was designed primarily for use on 35 mm (24×36) rangefinder-style cameras to help frame and compose with longer lenses.
Optics & Coverage
The finder supports 50 mm, 85 mm, 135 mm, and 180 mm lenses — making it quite versatile for various telephoto focal lengths.
Its design is “multi-shoe”: the optical tube can be pulled out and reversed, which allows switching between different framings for telephoto lenses.
It’s built to work with 24×36 format (i.e., standard 35 mm film) cameras.
This finder is especially valued by vintage camera enthusiasts who use longer Zeiss lenses and want a proper framing tool.
