Olympus Imaging Corporation (President: Masaharu Okubo) is pleased to announce the introduction of 2 new professional-quality telephoto zoom lenses for use with “Designed-for-Digital” SLR cameras. “ZUIKO DIGITAL ED 35-100mm F2.0” lens is scheduled to go on sale in October 2005, and the super-telephoto “ZUIKO DIGITAL ED 90-250mm F2.8” lens is scheduled to go on sale in December 2005.
 
“ZUIKO DIGITAL” lenses are interchangeable lenses that maximize the performance potential of the image sensor in “Designed-for-Digital” Olympus E-System digital SLR cameras. The two newly announced lenses feature an inner zoom mechanism that eliminates the need for the lens to extend or retract during zooming. They also boast uncompromising professional-grade specifications that ensure superb imaging performance. They are new-generation telephoto zoom lenses that fully realize the “Four-Thirds System” advantages of high mobility, high image-quality, superior brightness, and excellent close-up capability.
 

 

“ZUIKO DIGITAL ED 35-100mm(70-200mm*1) F2.0” features a wide zoom range that offers both the natural perspective of medium-telephoto zoom and the compressed perspective of telephoto zoom. It is the first*2 lens in the world to combine this versatile zoom range with a maximum aperture of F2.0 at any zoom setting

 

In addition to offering impressive 250mm(500mm*1) telephoto power, “ZUIKO DIGITAL ED 90-250mm(180-500mm*1) F2.8” lens is a fast-aperture, super-telephoto zoom lens that offers a maximum aperture of F2.8 at any zoom setting. And it’s the first zoom lens to combine a maximum aperture F2.8 with super-telephoto power -something that was previously available only in fixed focal lenses.

 

 
With the addition of the “ED 35-100 F2.0” and “ED 90-250mm F2.8” lenses to the previously released “ED 150mm F2.0” and “ED 300mm F2.8” fast-aperture, super-telephoto lenses, Olympus now offers an impressive line-up of “ZUIKO DIGITAL” super-telephoto lenses. As a result, users can shoot at fast shutter speeds and effectively blur background elements to suit their creative goals when taking portraits, wildlife, and sports photos.

 

ZUIKO DIGITAL ED 35-100mm F2.0:Main Features
 
1.  Expanded Shooting Capabilities of the World’s First*3 F2.0 Large-Aperture Telephoto Zoom Lens
  “ZUIKO DIGITAL ED 35-100mm F2.0” is the first 35-100mm (70-200mm*4) telephoto zoom lens in the world to offer a bright, F2.0 aperture at any zoom setting. Its sharp, clear imaging performance at F2.0 makes it ideal for shooting portraits, stage plays and concerts, nighttime sporting events under lights, and other subjects where fast shutter speeds or a shallow depth of
field are needed.

2.  1-Super-ED-Lens Element and 4-ED-Lens Elements for Minimal Chromatic Aberration
  1-Super-ED-lens element and 4-ED-lens elements are used to suppress the chromatic aberration that can occur with telephoto lenses. Thanks to the use of a Super ED element that has chromatic dispersion properties very similar to fluorite, resolving power and contrast are excellent, and chromatic aberration is suppressed to a greater degree than is possible with conventional optical glass.
 

3.  Floating Mechanism with a Minimum Focusing Distance of 1.4 meters
  The focusing system uses an advanced floating mechanism that assures a minimum focusing distance of only 1.4 meters. Imaging performance is excellent from infinity right down to the minimum focusing distance.
 
 
ZUIKO DIGITAL ED 35-100mm:Other Features
 
  Petal-Shaped Lens Hood with Polarizing Filter Adjustment Window
  The large, petal-shaped lens hood features a sliding window for easy filter rotation when using a polarizing filter.
 
ZUIKO DIGITAL ED 90-250mm F2.8:Main Features
 

1.  Expanded Shooting Capabilities of an F2.8, Large-Aperture, Super-Telephoto Zoom Lens
  “ZUIKO DIGITAL ED 90-250mm(180-500mm*5) F2.8” lens is an super-telephoto zoom lens that offers a bright, F2.8 aperture at any zoom setting. Its sharp, clear imaging performance at F2.8 makes it an ideal choice in situations that require fast shutter speeds or a shallow depth of field. It also instantly allows optimum framing for efficient sports and wildlife photography in situations where it is difficult to get close to the subject.

2.  3-ED-Lens Elements for Minimal Chromatic Aberration
  Three ED lens elements ensure maximum resolving power and contrast, and minimize the chromatic aberration that can occur with telephoto lenses.
 
3.  Inner Focusing Mechanism with a Minimum Focusing Distance of 2.5 Meters
  An inner focusing mechanism is used to assure a minimum focusing distance of only 2.5 meters. Imaging performance is excellent from infinity right down to the minimum focusing distance.
 
Shared Features
 
  Reliable, Dust and Water Droplet Resistance Construction
  External components are thoroughly sealed to ensure high resistance to dust and moisture. As a result, the lens can withstand the rigorous demands of professional shooting under adverse conditions.
 
  Responsive Coreless Motor for High-Speed Auto-focusing
  The auto-focus drive system uses a highly responsive core-less motor to assure faster auto-focusing and stress-free shooting.
 
  Focus Limit Switch and Focus Stop Button
  A focus limit switch allows focusing time to be reduced by limiting the focus range to far distances or near distances. In addition, there is a focus stop button to prevent the auto-focus system from responding to foreground movement after correct focus on the primary subject has been achieved.
 
  Circular Aperture Diaphragm
  A circular aperture diaphragm with 9 blades ensures smooth background blurring at larger apertures.
 
  Multi-Coated Lens Elements
  Multi coating ensures minimal ghosting and flaring in backlit conditions. (The “ZUIKO DIGITAL ED 35-100mm F2.0” features a newly developed multi coating that suppresses reflection at a wide range of wavelengths.)
