The Olympus M.Zuiko Digital ED 8-25mm f/4 PRO Lens is a dynamic ultra-wide Micro Four Thirds zoom lens with the equivalent full-frame format zoom range of 16-50mm.
Its sophisticated optical design, which includes a variety of aspherical, low dispersion, and high refractive index elements, reduces both chromatic and spherical aberrations throughout the zoom range for notable clarity, sharpness, and colour accuracy. A ZERO lens coating has also been applied to improve contrast when working in strong lighting conditions.
Beyond the advanced lens design, this zoom is also characterized by its constant f/4 maximum aperture, as well as its durable weather-sealed construction for working in a variety of conditions. Additionally, a Movie & Still Compatible autofocus system achieves fast, smooth, and silent focusing performance, and a manual focus clutch affords instant switching between focusing methods.
The 16 lens 10 group configuration including special lenses such as Super ED, ED, and EDA lenses, thoroughly eliminates all kinds of aberrations including chromatic aberration. Enjoy high resolution across the entire zoom range. Furthermore, incorporating a large DSA lens significantly reduces sagittal comatic aberration. This design delivers high point image reproduction from the center to the edges of the image even at the widest aperture setting.
Zuiko Extra-low Reflection Optical Coating
Despite being a 16mm equivalent ultra-wide-angle lens, the optical design and coating are optimized to thoroughly suppress ghosts and flaring during backlit shooting.
Close-up shooting performance
This lens delivers a maximum shooting magnification of 0.42x1 that allows you to get up close with subjects for intense shots that rival a half-macro lens. The closest focusing distance is 0.23 meters across the entire zoom range, offering greater freedom over artistic shots with variations in subject size and perspective in close-up shooting.
