Overview

The Carl Zeiss Jena Flektogon 25mm f/4 is a pioneering retrofocus wide-angle lens praised for its outstanding image quality and smooth, precise build. It offers a useful close-focus distance of 19cm, making it versatile for macro, portraits, and landscapes. However, by 1967 its design was considered dated, and some samples may be soft. It suits photographers seeking an affordable, classic Zeiss lens with a cult following, especially for travel or creative wide-angle work.
