    105mm · f/2.5

    Overview

    The Spiratone 105mm f/2.5 is a compact, pre-set aperture T-mount lens with single coating. Its main weaknesses are strong flare and low contrast, especially backlit. Wide open at f/2.5, sharpness is mediocre but usable for portraits; stopped to f/4 or smaller, it becomes respectable. Colors are good, but contrast is short. Bokeh is decent. It suits budget-conscious photographers willing to work around its limitations, particularly for portraiture when stopped down.
