Panasonic Leica DG Vario-Elmarit 50-200mm F2.8-4.0 ASPH Power O.I.S.

This is a zoom lens for Micro Four Thirds, covering 50-200 mm (100-400 mm equivalent) and a maximum aperture of f/2.8-4.0. Released in 2018, it weighs 655 g, is weather-sealed and includes optical stabilization. That combination suits portrait photography.

It is a high-end telephoto zoom lens designed for Micro Four Thirds mirrorless cameras, offering a 100-400mm equivalent focal length range. Its variable maximum aperture of f/2.8-4.0 provides flexibility in various lighting conditions, while the advanced optical design—including aspherical, ultra extra-low dispersion (UED), extra-low dispersion (ED), and ultra-high refractive index (UHR) elements—ensures sharp, high-quality images with minimal aberrations. The Power Optical Image Stabilizer (O.I.S.) compensates for camera shake, delivering sharper handheld shots. Its robust, weather-sealed construction makes it suitable for use in challenging environmental conditions.
