Overview

The Samsung D-Xenon 100mm F2.8 macro offers true 1:1 macro and doubles as a portrait lens, with a 100mm focal length (153mm equivalent on APS-C) and f/2.8 aperture for shallow depth of field. Optically, it delivers high resolution at wider apertures, peaking at f/8, but resolution drops steeply at smaller apertures and is poor at f/32; chromatic aberration is average but visually minor. Build includes a polycarbonate barrel, deep rubber focus grip, and focus lock, but autofocus is noisy. It suits Pentax/Samsung DSLR users wanting a versatile macro and portrait lens, though those needing quiet AF may look elsewhere.
