The Leica DG Vario-Elmarit 50-200mm f/2.8-4 ASPH. POWER O.I.S. Lens from Panasonic is a 100-400mm equivalent zoom designed in collaboration with Leica for Micro Four Thirds cameras. The long reach is complemented by a bright f/2.8-4 maximum aperture range, which benefits working in low-light conditions and also affords control over the depth of field for isolating subjects. The optical design incorporates several low dispersion elements, two aspherical elements, and an ultra-high refractive index element to control both chromatic and spherical aberrations for improved clarity and sharpness. A Nano Surface Coating has also been applied to limit flare and ghosting for increased contrast and colour fidelity when working in strong lighting conditions.

Benefitting both stills shooting and video recording, a 240 fps high-speed AF motor offers quick, quiet, and precise autofocus performance. Also, a POWER Optical Image Stabilizer will compensate for camera shake and works with Panasonic's Dual I.S. and Dual I.S. 2.0 in-camera stabilization functions to minimize the appearance of camera shake. Additionally, the physical design of the lens is dust- and moisture-resistant, as well as freeze-proof, for use in inclement shooting conditions.

• With a 100-400mm equivalent focal length range on Micro Four Thirds cameras, this telephoto prime is well suited to working with distant subject matter.
• Bright f/2.8-4 maximum aperture range excels when working in difficult lighting conditions and provides increased control over depth of field.
• Two ultra extra-low dispersion elements and two extra-low dispersion elements minimize various aberrations in order to produce a high degree of clarity, sharpness, and color accuracy.
• Two aspherical elements and one ultra high refractive index element help to reduce distortion and spherical aberrations for improved sharpness and accurate rendering throughout the zoom range.
• Nano Surface Coating has been applied to individual elements to reduce flare and ghosting for improved contrast and color neutrality.
• POWER Optical Image Stabilizer minimizes the appearance of camera shake for sharper handheld shooting, and also supports the Dual I.S. and Dual I.S. 2.0 functions for increased stabilization performance.
• A 240 fps AF motor offers fast, precise, and near-silent focusing performance to benefit both stills shooting and video recording applications.
• Splash, dust, and freezeproof design benefits working in inclement weather conditions down to -14°F.
• Compatible with optional 1.4x and 2x teleconverters to further extend the effective reach.
