28mm · f/2.8
The Revuenon 28mm f/2.8 Auto is an inexpensive M42-mount vintage lens of uncertain origin, possibly made by Enna Munchen or Tomioka. It offers sharp center resolution and a unique, blur-like bokeh. Build quality is not as good as Takumar. It suits budget-conscious photographers seeking a compact wide-angle with character, though its soft corners and unknown manufacturer may deter purists.
