70–150mm · f/3.8
The Vivitar MC 70-150 mm f/3.8 Kino, made by Kiron, offers solid build quality with a two-ring design that avoids zoom creep, a built-in hood, and smooth focusing. Optically, it is sharp at 70mm wide open but soft at 150mm f/3.8, improving by f/8. Contrast and shadow detail are excellent, with smooth bokeh and minimal fringing. However, its optical performance does not match the Nikon 75-150mm f/3.5, showing corner softness. It suits budget-minded photographers seeking a compact, durable telephoto zoom for portraits and macro (1:4) on crop-sensor cameras.
