The Panasonic Lumix G - Leica 100-400mm F4-6.3 II is a telephoto zoom lens designed for the Micro Four Thirds system. It offers a focal length range of 100-400mm, which is equivalent to 200-800mm in full-frame terms[1]. With this range, it provides users with the ability to capture distant subjects with ease.
The lens has an aperture range of f/4 to f/22, allowing for a wide range of control over depth of field and low-light performance. Its compact design makes it a convenient choice for photographers who want the versatility of a telephoto zoom lens without sacrificing portability.
The lens features a .5x maximum magnification, which is equivalent to a 35mm maximum magnification. This allows photographers to capture fine details and close-up shots even when shooting from a distance.
For image stabilization, the lens is equipped with POWER O.I.S. (Optical Image Stabilizer) technology, which helps minimize the appearance of camera shake and allows for sharper handheld shots. It is also compatible with Dual I.S., a feature found in Lumix G cameras that combines in-lens and in-body stabilization for even greater stability.
The lens include a rounded 9-blade diaphragm for smooth and pleasing bokeh, a rotating tripod collar for improved stability when shooting on a tripod, and a built-in hood for added protection against stray light and lens flare. It is also designed to be dust, splash, and freeze resistant, making it suitable for outdoor photography in various weather conditions.
