Powerful Ultra-Wide Zoom Lens

The Olympus M.Zuiko Digital ED 8-25mm f/4 PRO Lens is a dynamic ultra-wide zoom lens for Micro Four Thirds cameras, giving you an 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.


  • Constant f/4 maximum aperture enables consistent low-light performance and selective focus control throughout the zoom range
  • The lens construction integrates one DSA (Dual Super Aspherical) element, one ED (extra-low dispersion) element, two aspherical ED elements, one Super ED element, one HR (high-refractive index) element, one Super HR element, and one HD element elements into its design to minimize 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 minimize 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
  • Manual focus clutch allows the focusing ring to be quickly pulled into place for direct, intuitive focus control
  • Programmable L-Fn (lens function) button for easily accessible settings adjustment
  • Dust-, freeze-, and drip-proof design ensure the lens' performance in inclement and harsh conditions
  • Front optic features protective fluorine coating
  • Rounded seven-blade diaphragm produces a smooth bokeh quality

High resolution across the entire zoom range

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.

Reliable Performance

  • Dustproof, splashproof, and -10°C freezeproof With IPX1 equivalent dustproof and splashproof performance plus freezeproofing to -10°C you can push on in rain and snow with peace of mind.
  • Fluorine coating is used on the front most lens. Even if the front most lens gets dirty, it can be quickly cleaned with a blower or cloth.
  • Φ72mm filter thread. Enjoy a greater range of photographic expression.
  • Designed for a superior hold. The zoom ring's position at the front of the lens allows for more space between the lens and camera grip.
  • The L-Fn (lens function) button is placed in a location that is easy for the left thumb to reach for easy controls while holding the lens.
  • The Manual Focus Clutch mechanism makes instant switching to manual focus easy by simply pulling the focusing ring toward you.
