    Overview

    The Spiratone 18mm f/3.5 is an ultra-wide manual-focus lens for vintage mounts. Optically, it is soft in the corners and exhibits chromatic aberration, but center sharpness is acceptable when stopped down. Build quality is typical of its era: all-metal with smooth focus, but the glass may yellow with age. It suits enthusiasts of classic lenses who want an inexpensive ultra-wide for film or adapted digital use, though modern alternatives offer better performance.
