The first in the newly created “M.ZUIKO PRO” category, the OLYMPUS M. Zuiko Digital ED 12-40mm f2.8 PRO Lens is a zoom lens covering wide angle and long telephoto. It is compatible with the Micro Four Thirds system. It covers a 35mm equivalent focal length of 24-80mm, and features a constant f/2.8 maximum aperture for a reliable low-light performance and shallow depth of field control. This lens integrates an array of high grade optical components, including Dual Aspherical, High Refractive, and ED lens elements. All the lens elements are configured in nine groups to assure the highest level of image reproduction. A high-speed AF linear motor drive system, with MSC (movie and still compatible), ensures fast and quiet auto focusing for high-quality sound recording. The durable metallic construction is splash-, dust-, and freeze-proof for rugged performance in harsh, inclement conditions.
- Superior Optical DesignThis lens construction features 14 elements in nine groups, including one aspherical ED (extra-low dispersion) element, two aspherical elements, one DSA (Dual Super Aspherical) element, two ED (extra-low dispersion) elements, one HD element, and two HR (high-refractive index) elements, to ensure superior image quality with minimized aberration, distortion, and color fringing.
- Movie & Still Compatible (MSC)A high-speed AF linear motor drive system ensures fast, smooth and quiet focusing performance. It also support the Movie & Still Compatible (MSC), which means it is so quiet that the sound will not be picked up during video recording.
- Manual Focus SupportWith a manual focus clutch, you can quickly and intuitively switch between auto and manual focusing control.
- Tough BuildThe metallic construction is dust-, freeze-, and drip-proof, ensuring hassle-free performance in harsh environments.
- Circular Aperture MechanismThe seven-blade circular aperture diaphragm achieves a beautiful background blur effect.
