Quick Ultra-Wide Zoom. With a 35mm-equivalent focal length of 16-50mm, the Olympus 8-25mm f/4 ED PRO covers the ultra-wide to portrait-length range. 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. It’s ideal for outdoor shooting and dramatic landscapes.

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 8-25mm’s ten-group/sixteen element design features one Dual Super Aspherical (DSA) element, one extra-low dispersion (ED) element, two aspherical ED elements, one Super ED element, one high-refractive index (HR) element, one Super HR element, and one HD element. This advanced optical formula minimizes aberrations, distortion, and color fringing throughout the zoom range while retaining overall image sharpness, clarity, and fidelity.

Compact Weather-Sealed Build. This lens is just under 3.5 inches long and weighs in at slightly under 1 pound so it won’t weigh you down one bit, and its dust-, freeze-, and drip-proof build allows use in even the least-desirable conditions.
