Panasonic Leica 100-400mm f/4.0-6.3 ASPH OIS

The Panasonic Leica DG Vario-Elmar 100-400mm f/4.0-6.3 ASPH Power O.I.S. is a high-precision optical solution developed for the Micro Four Thirds system, providing a focal range equivalent to 200-800mm on full-frame sensors. The optical configuration consists of twenty elements in thirteen groups, including one aspherical extra-low dispersion lens, two extra-low dispersion lenses, and one ultra extra-low dispersion lens to effectively correct chromatic fringing and distortions throughout the zoom range. The Power O.I.S. stabilization system is designed to mitigate camera shake typical of long focal lengths, interfacing with the Dual I.S. technology of compatible Lumix cameras for combined compensation. Focusing is managed by a linear motor operating at 240 fps, ensuring the operational speed required for tracking dynamic subjects and silent fluidity during video content acquisition. The exterior structure features a weather-sealed design resistant to environmental elements and dust, complemented by an integrated retractable lens hood and a rotating tripod mount that allows for rapid camera repositioning. This original version is characterized by its compactness relative to the focal length offered, though it does not support the use of external teleconverters.
