Overview

The Spiratone Expandar 28mm f/2.8 Auto Wideangle is a vintage third-party lens with mixed performance. Optically, it delivers very sharp center sharpness wide open, comparable to Takumar lenses (luisalegria). However, corners are poor even on APS-C, with inconsistent sharpness across the frame and severe flare when pointed near the sun (luisalegria). Build quality is above average for its era, with glossy enamel and chrome accents, but the focus mechanism can become gummed up over time, requiring careful cleaning and lubrication (Kathmandu). It suits users interested in vintage character or project lenses, but not those needing edge-to-edge sharpness or flare resistance.
