70–210mm · f/2.8–4
Overview
The Vivitar MF Series 1 70-210mm f/2.8-4 Apochromatic (Cosina) is the fourth version, with variable aperture and 1:2.5 macro. It is lighter but has inferior build quality compared to earlier versions. Optically, it is not sharp wide open, with blooming and softness at the wider end, improving when stopped down. Bokeh is smooth. It suits videographers who prioritize bokeh over sharpness and prefer a lighter lens.
