Olympus Press Release

Compact and lightweight, high-image quality standard lens in M.ZUIKO PREMIUM series

M.ZUIKO DIGITAL 25mm F1.8 (50mm, 35mm equivalent), Micro Four Thirds System standard compliant

Olympus Imaging Corporation (President: Haruo Ogawa) is pleased to announce the M.ZUIKO DIGITAL 25mm F1.8 (35mm equivalent: 50mm) Micro Four Thirds System standard compliant, M.ZUIKO PREMIUM series compact and lightweight, high-image quality standard lens scheduled for release in late February.

The new M.ZUIKO DIGITAL 25mm F1.8 standard high-image quality lens features a bright aperture value of F1.8, and focal length of 50mm (35mm equivalent) in a compact, lightweight form. Because this lens provides an angle of view that is close to a natural field of view just as is seen by the naked eye, this is the perfect everyday lens for snapshots, portraits, and landscapes. The large F1.8 aperture of this lens will offer beautiful defocusing effects, and reducing subject blur in dark indoor shots for more enjoyable shooting, making this the perfect first interchangeable lens.

This lens is an M.ZUIKO PREMIUM series lens that meets the ZUIKO QUALITY of the popular M.ZUIKO DIGITAL 45mm F1.8, for high resolution from the center to the edges of the image while remaining compact and lightweight.

Main Features

ZUIKO QUALITY enables high optical performance from the widest aperture setting
Close-up shooting performance up to 25 cm away
Fast, silent AF so you never miss a shot

Main Features Details

1.ZUIKO QUALITY enables high optical performance
The M.ZUIKO DIGITAL 25mm F1.8 is a high-quality, standard lens that produces beautiful defocusing effects and high resolution, along with the same high optical performance of the popular M.ZUIKO DIGITAL 45mm F1.8, while maintaining a compact and lightweight size.

Traditional 50mm DSLR standard lenses generally use a Gauss-type configuration, however, to achieve a smaller form, fast and quiet AF, a new lens design for the digital age with an inner focusing system was used. To reduce aberration from the center to the periphery, 9 lenses including an aspherical lens are lavishly used, demonstrating clear and sharp optical performance.

Also, by using the Olympus-original ZERO (Zuiko Extra-low Reflection Optical) coating, ghosts and flaring are suppressed for clear depictive performance even in backlit and other unfavorable shooting conditions.

As a standard lens in the M.ZUIKO PREMIUM high-quality single-focal-length lens series, this lens features sharpness and soft defocusing effects that make it the perfect lens for snapshots, portraits, and landscape photography.

Just as other lenses in the M.ZUIKO PREMIUM series, the M.ZUIKO DIGITAL 25mm F1.8 features the same attention to detail in textures, giving it a unified feel with the OLYMPUS PEN and OM-D series cameras. This lens is available in black and silver to match perfectly with your camera.

2.Close-up shooting performance up to 25 cm away
The M.ZUIKO DIGITAL 25mm F1.8 can shoot up to 25 cm away for close-up photography, with a maximum magnification factor of 0.24x at 35mm equivalent (0.12x), able to fit a postcard sized shot (A6 equivalent) in the screen full size. When shooting close-ups of tableware or food, the aperture setting of F1.8 creates soft defocusing effects for tabletop photos that are a touch different than the average.
By combining this lens with the separately-sold Macro Conversion Lens MCON-P02, close-up shooting up to 17m away is possible, for easy macro photography at a maximum shooting magnification of 0.436x at 35mm equivalent (0.218x).

3.Fast, silent AF so you never miss a shot
The M.ZUIKO DIGITAL 25mm F1.8 is equipped with the MSC (Movie & Still Compatible) mechanism inner focusing system for fast, smooth, silent, and high-precision AF (auto focusing). When used in combination with FAST AF on OLYMPUS PEN and OM-D series cameras, you'll never miss a shot.
This quiet AF is perfect for capturing still images and movies in quiet scenes.
