Albinar ADG 28mm f/2.8 Lens for Pentax K Mount

The Albinar ADG 28mm f/2.8 Macro is a manual focus wide-angle prime lens produced for Pentax’s K-mount SLR system. At 28mm with an f/2.8 maximum aperture, it delivers a moderate wide-angle field of view well suited to landscape, architecture, interior, street, and environmental photography, with useful light gathering capability for shooting in lower light conditions. A macro setting provides closer minimum focusing capability than standard operation allows, extending its versatility for close-up work on smaller subjects without requiring a dedicated macro lens. The ADG designation indicates a specific optical formula variant within Albinar’s lens lineup. Fully manual operation covers both focus and aperture adjustment directly on the lens. Albinar was a third-party lens brand producing accessible alternative optics during the film SLR era. Compatible with Pentax K-mount film and digital SLR bodies, and adaptable to mirrorless and other camera systems via third-party Pentax K-mount adapters.
