100mm · f/2.8
The Vivitar 100mm f/2.8 macro lens, likely a Kiron build, offers solid construction with high-grade plastic, above Nikon consumer-grade. Optical quality is typical for a macro prime, though bokeh highlights can be hard-edged. It features a long focus throw for precise manual focusing, a built-in hood, and a working distance of about 7-8 inches at 1:1. Suits macro photographers and those comfortable with manual focus; not ideal for smooth bokeh in portraits.
