    Overview

    The Tamron SP 28-105mm f/2.8 LD Aspherical IF Adaptall-2 model 176A is a fast standard zoom known for its versatile f/2.8 aperture and solid build. Optically, it delivers decent sharpness at telephoto lengths but is soft wide open at wider focal lengths, with significant vignetting and chromatic aberration. It is heavy and large, taking 82mm filters, and lacks a tripod collar. Best suited for event or wedding photographers who prioritize the constant aperture and range over ultimate sharpness.
