    28–105mm · f/2.8–3.8

    Overview

    The Cosina 28-105mm f/2.8-3.8 MC AF is a push-pull zoom lens with so-so build quality, prone to dust ingress and lacking a zoom lock. Optically, it offers creamy bokeh at wide apertures but inconsistent autofocus at the telephoto end, improving at f/7.1; macro performance is poor. The lens is noisy and lacks a distance scale. It suits budget-conscious shooters seeking a versatile walkabout lens on crop bodies, especially those comfortable with manual handling.
