Bell & Howell — vintage manual-focus 28mm f/2.8 wide-angle prime, sold across multiple SLR mounts
Bell & Howell, the American cine-equipment maker, put its name on Japanese-made 35mm SLR lenses sold through department-store and mail-order catalogues from the 1970s into the early 1980s. The 28mm f/2.8 wide-angle prime was one of the more widely stocked entries in that lineup.
Like most catalogue-brand primes of the period it is fully manual, with a click-stopped aperture ring and an all-metal barrel, and was offered across the common SLR fittings of the day so buyers could match it to whatever body they owned. Element count and filter thread are not confirmed from available sources.
Optically it sits with the general run of independent 1970s wide-angle primes: usable center sharpness stopped down, softer corners wide open, and modest contrast next to contemporary first-party glass.
These turn up cheaply and inconsistently branded secondhand. Check that the aperture ring clicks cleanly through its range, the diaphragm blades close without oil staining, and the mount fitted matches the camera.
