The Lumix S 24-105mm f/4 Macro O.I.S. from Panasonic is a flexible zoom, featuring a constant f/4 maximum aperture, for L-mount mirrorless cameras. In regard to its optical design, a series of low dispersion and aspherical elements are used to control a variety of aberrations, color fringing, and distortion in order to realize a high degree of sharpness, clarity, and color accuracy. Balancing its optical performance, this zoom is also unique due to its 1:2 maximum magnification ratio and 11.8" minimum focusing distance to suit working with close-up subjects. Additionally, an Optical Image Stabilizer helps to control the effects of camera shake for sharper handheld shooting, and the lens sports a weather-sealed design for use in harsh conditions. Constant f/4 maximum aperture maintains consistent illumination throughout the zoom range. One ultra extra-low dispersion element and two extra-low dispersion elements greatly reduce chromatic aberrations and color fringing in order to produce a high degree of clarity and color accuracy. Optical Image Stabilizer minimizes the appearance of camera shake for sharper handheld shooting and also supports 5-Axis Dual I.S. 2 for increased stabilization performance.
