Olympus Imaging Corporation (President: Masaharu Okubo) today announced the upcoming launch of the ZUIKO DIGITAL 25mm f2.8, a thin, lightweight single-focus standard pancake-type lens fully compliant with the Four Thirds System standard for digital SLR cameras and scheduled for release in the middle of April, 2008.
Main Features

1. Thin, lightweight pancake-type lens with an overall length of 23.5 mm and weight of 95 grams
2. Digital-dedicated, high-image-quality design
3. Excellent close-up shooting capability
4. Screw-in aluminium lens cap

ZUIKO DIGITAL is a series of interchangeable lenses designed especially for use with digital SLR cameras. Featuring compliance with the Four Thirds System standard, these dedicated lenses maximize the potential of the high-performance image sensors used in digital SLRs.

The newly developed ZUIKO DIGITAL 25mm f2.8 is a thin, lightweight single-focus standard pancake-type lens with a focal distance equivalent to 50 mm on a 35 mm camera lens. It offers both excellent portability thanks to the compact and lightweight advantages of the Four Thirds System and very sharp, clear imaging performance.

The lens has an overall length of 23.5 mm. When combined with the already released E-410 or the upcoming E-420 digital SLR camera, the total length including the camera body and lens is only 76.5 mm. The result is an easy-to-store, easy-to-carry camera system with go-anywhere portability. And when the lens with E-420 is used, "AF Live View" function, which makes Live View shooting easier and more convenient than ever, is available.

With a focal distance equivalent to 50 mm on a 35 mm film camera lens, this standard pancake-type lens provides an image angle very close to that of the naked eye. The result is a near-natural visual field that makes this an ideal standard lens for daily use, whether for simple snapshots or for more sophisticated portrait and landscape shooting.


1. Thin, lightweight pancake-type lens with an overall length of 23.5 mm and weight of 95 grams
Mastery of the latest optical design technology has resulted in a thin, lightweight pancake-type lens with an overall length of only 23.5 millimetres and weight of 95 grams. When this lens is mounted on the currently available E-410 or the just announced E-420 digital SLR camera, the total length of the camera body and lens is still only 76.5 mm. The result is a camera system that is easy to store and easy to carry, offering go-anywhere portability. With its compact, lightweight design, this highly portable lens is ideal for daily use, perfect for a wide range of photographic opportunities from snapshots to portrait and landscape shooting.
2. Digital-dedicated, high-image-quality design
The focal distance is equivalent to 50 mm on a 35 mm camera lens. Double-sided aspherical lens components are employed to reduce the lens length and provide optimal aberration correction, achieving a sharp, clear image just like a single-focus lens. A specially formulated lens coating optimized for shooting against light minimizes ghosts and flares. With a high open aperture f-value of 2.8 and a circular aperture diaphragm, this lens lets you create beautiful soft-focus images and take advantage of natural defocusing effects.
3. Excellent close-up shooting capability
Close-up shooting is possible at a minimum distance of 13 centimeters from the front of the lens. The possibility of positive challenge to the shooting subject will expand the field of photography.
4. Screw-on aluminium lens cap
The lens cap is made of aluminium and screws onto the lens. This ensures a sleek, streamlined exterior appearance.
