Standard wide-angle to portrait-length zoom lens is designed for Micro Four Thirds mirrorless cameras and provides a 24-90mm equivalent focal length range.Constant f/4 maximum aperture enables consistent performance throughout the zoom range and helps to achieve a sleek and lightweight physical design.The lens construction integrates two aspherical elements, one DSA (Dual Super Aspherical) element, two extra-low dispersion elements, one Super HR (high-refractive index) elements, and two HR elements into its design to minimise aberrations, distortion, and colour fringing throughout the zoom range while also contributing to overall image sharpness, clarity, and colour accuracy.A ZERO (Zuiko Extra-low Reflection Optical) coating has been applied to individual elements to minimise lens flare and ghosting for improved contrast and colour fidelity when working in strong lighting conditions.Movie & Still Compatible (MSC) autofocus system benefits both photo and video applications due to its smooth, quiet, and fast performance.Minimum focusing distance of 4.7″ at the wide end and 9.1″ at the tele end pairs with an impressive 0.25x maximum magnification ratio to suit working with close-up subjects.Dust-, freeze-, and drip-proof design ensure the lens’ performance in inclement and harsh conditions.Rounded seven-blade diaphragm produces a smooth bokeh quality.
