Overview

The Enna München Tele-Ennalyt 135 mm f/2.8 is a fast, budget-friendly M42 telephoto lens with a Sonnar-inspired design and 10 aperture blades. Optically, it suffers from mediocre color rendering, softness especially at the edges, heavy flare due to poor coating, and potential fringing. Build quality is basic plastic/aluminum with loose rings, and the 1980s version is particularly cheap-feeling. Its main appeal is hackability: it disassembles easily for custom aperture modifications without ruining a classic lens. It suits tinkerers on a tight budget, but for image quality, many better 135mm options exist.
