Overview

The Formula 5 28mm f/2.8 MC is a rebranded Accura lens, likely manufactured by Mitake optical works in Japan. It feels solid with a large 58mm filter thread. Optical quality is typical of cheap 28mm lenses of the era, offering reasonably good quality. It suits budget-conscious shooters seeking an affordable, functional wide-angle for M42 or Konica mounts, though it lacks exceptional sharpness or character.
