Overview

The Enna München Tele-Ennalyt 400 mm f/4.5 is a vintage medium-format telephoto lens introduced in 1958, typically found in M42 or Exakta mount. It features a rear drop-in filter slot and a focus ring that can rotate beyond the marked 5 m minimum to approximately 4.5 m. Build quality is solid but the focus barrel may be stiff. Optical performance is not detailed in the excerpts, but the lens covers medium format comfortably. It suits photographers comfortable with manual operation and adapting to mirrorless cameras, though Exakta mount requires adapters.
