Alpa 90mm f/2.5 Alfitar Auto Lens Review

The Alpa 90mm f/2.5 Alfitar Auto is a vintage manual-focus lens from the Swiss Alpa system, a niche rangefinder platform prized by collectors and medium-format enthusiasts. This particular unit is offered used in bargain condition at $470, meaning visible wear and functional compromises are likely. The 90mm focal length on the Alpa mount historically served as a short telephoto for portraiture and detail work, with the f/2.5 aperture offering moderate speed for its era.

Alpa glass is rare and adapting it to modern digital bodies can be complex, often requiring custom solutions or acceptance of limited functionality. The Alfitar Auto branding suggests a third-party or licensed variant rather than a first-party Alpa optic, which may affect optical quality and collector value. At this price point in bargain condition, it's a curiosity for Alpa system users or vintage lens experimenters rather than a practical workhorse for contemporary shooting.
