70–210mm · f/2.8–4
The Vivitar Series 1 70-210mm f/2.8-4 VMC (Cosina) is the fourth version of this lens, known for its smooth bokeh but softer wide-open sharpness, especially at the wider end, with blooming and softness that improve when stopped down. Build quality is lighter than earlier versions but sacrifices grip and feel. It offers a 1:2.5 close-up capability. This lens suits videographers or photographers who prioritize smooth bokeh over peak sharpness and prefer a lighter, variable-aperture telephoto zoom.
