Overview

The Panasonic 100mm f/2.8 Macro is an exceptionally compact and lightweight lens (298g) for a full-frame macro, matching the size of the Lumix f/1.8 primes. It offers 1:1 magnification, fast and accurate autofocus, and minimal focus breathing. Build quality is high despite plastic construction, with weather resistance and a well-damped focus ring. Optically, it is very sharp with good contrast, though some note it is not an f/2 lens. It suits macro, portrait, and general telephoto use, especially for those wanting a compact, multi-purpose lens.
