Overview

The Nikon Series E 100mm f/2.8 is a compact, lightweight manual-focus lens praised for its sharpness and solid build, with a metal mount and filter thread. Optical strengths include good contrast and flare control, but it is slower than f/1.8 alternatives and has less shallow depth-of-field. Weaknesses include purple axial chromatic aberration in early prototypes. It suits photographers wanting a portable, affordable portrait lens for APS-C or film, though it lacks autofocus and may not meter on entry-level cameras.
