A flexible zoom covering a popular focal length range, the M.Zuiko Digital ED 12-40mm f/2.8 PRO from Olympus is a wide-to-portrait-length 24-80mm equivalent lens for Micro Four Thirds mirrorless cameras. 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 color 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/2.8 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.

Standard wide-angle to portrait-length zoom lens is designed for Micro Four Thirds mirrorless cameras and provides a 24-80mm equivalent focal length range.
Constant f/2.8 maximum aperture enables consistent low-light performance and selective focus control throughout the zoom range.
The lens construction integrates one aspherical ED (extra-low dispersion) element, two aspherical elements, one DSA (Dual Super Aspherical) element, two extra-low dispersion elements, one HD element, and two HR (high-refractive index) elements into its design to minimize aberrations, distortion, and color fringing throughout the zoom range while also contributing to overall image sharpness, clarity, and color 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 color 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 lets you quickly pull the focusing ring 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.
Rounded seven-blade diaphragm produces a smooth bokeh quality.
