Sirius's wide-angle for Fujica AX — a budget 28mm f/2.8 from an obscure brand.
The Sirius 28mm f/2.8 is a wide-angle prime from the Sirius brand for Fujica AX-mount cameras. Sirius was a trade name used for third-party and OEM lenses marketed in various regional markets during the 1970s–1980s.
The lens delivers 28mm at f/2.8 maximum aperture with Fujica AX bayonet coupling, manual focus, manual aperture, and full-frame 35mm coverage. Budget construction typical of third-party AX-mount glass.
The 28mm focal length provides a classic wide-angle perspective for documentary and street photography. The Fujica AX mount limits modern adaptation options, making this primarily useful with compatible Fujica AX bodies.
Test Fujica AX coupling and aperture ring operation. Inspect elements for clarity. Confirm adapter availability before considering modern mirrorless adaptation.
