Leica DG Vario-Elmar 100-400 mm f/ 4.0-6.3 ASPH PowerOIS
100–400mm · f/4–6.3
Overview
The Leica DG Vario-Elmar 100-400mm f/4.0-6.3 ASPH PowerOIS offers exceptional sharpness at wider focal lengths, with some softening at 400mm. Chromatic aberration and vignetting are well controlled. Build quality is impressive with all-metal construction and weather-sealing, though the zoom mechanism may feel tight. The lens is compact and lightweight for its 200-800mm equivalent reach, but the slow variable aperture limits depth-of-field. Autofocus is fast and quiet. It suits outdoor photographers needing extreme reach in a portable package, especially with Dual IS on Panasonic bodies.
