Fast Normal-Range Zoom. With a 35mm-equivalent focal length of 24-90mm, the Olympus 12-45mm f/4 ED PRO covers the wide to portrait length range. This lens’s 0.5x maximum magnification, 1:2 macro reproduction ratio, and 4.7-inch minimum focusing distance make it particularly well suited for close-ups and portraiture, but it’s also an excellent all-around lens. The f/4 aperture isn’t exactly supersonic in terms of speed but it remains constant across the range, making it a good choice for still shooters and videographers alike.

Movie and Still Compatible Autofocus. The linear AF motor gives you smooth, fast, and accurate autofocus performance. It also has the MSC designation, meaning it also works great for shooting video.

High-Quality Optics. The 12-45mm features one Dual Super Aspherical element, two aspherical elements, two extra-low dispersion elements, one super high-refractive index (HR) element, and two high-refractive index elements. This advanced optical formula minimizes aberrations, distortion, and color fringing throughout the zoom range while retaining overall image sharpness, clarity, and fidelity.

Ultra-Compact Weather-Sealed Build. This lens is just under three inches long and weighs in at slightly over half a pound, making it among the smallest, lightest, fixed-aperture zooms on the market. Its dust-, freeze-, and drip-proof build allows use in even the least-desirable conditions.
