Panasonic G Leica DG Vario-Elmar 100-400mm f/4-6.3 Aspherical 100-400mm
The 200-800mm equivalent focal length and POWER O.I.S. stabilization enable sharp handheld telephoto captures across its 20-element optical design. A splash-proof construction and 984g weight—significantly smaller than comparable DSLR lenses—make it a portable, all-weather tool. Ideal for bird and wildlife photographers who need a lightweight super-telephoto for hand-held shooting in variable conditions.
