RICOH IMAGING EUROPE S.A.S is pleased to introduce the HD PENTAX-D FA FA 28-105mm F3.5-5.6ED DC WR. This new compact, lightweight standard zoom lens provides a focal-length range from wide angle to medium telephoto.

Despite its compact, highly maneuverable body, this versatile zoom lens is designed to accommodate the image circle of a large 35mm full-frame image sensor, thanks to the adoption of state-of-the-art optics and high-performance optical elements. When mounted on the PENTAX K-1 camera body, it delivers high-resolution imaging power, making it an ideal everyday lens for the new 35mm full-frame digital SLR camera.

Main Features

1. Standard zoom lens covering most frequently used ranges
This standard zoom lens accommodates the image circle of a 35mm full-frame image sensor, and covers focal lengths between 28mm wide angle and 105mm medium telephoto. By incorporating the latest optics and a number of high-performance optical elements, it retains a sufficient brightness level even at edges of the image field, while effectively compensating for various aberrations. It delivers high-resolution images by optimising the imaging power of the PENTAX K-1’s (approximately) 36.4 effective megapixels. Its compact, lightweight body and excellent cost performance make this lens an ideal regular lens for the PENTAX K-1.

2. Excellent image description, complementing the full-frame digital SLR camera performance
In its 15-element, 11-group optics, this zoom lens incorporates two high-precision aspherical optical elements, one ED (Extra-low Dispersion) glass optical element and one anomalous-dispersion glass optical element, to deliver bright, sharp images with minimal chromatic and spherical aberrations. Since its optics are designed to assure ample resolving power for the large, high-pixel image sensor, it produces well-defined, fine-detailed images.

3. HD Coating to improve image description
This lens is treated with the high-grade, multi-layer HD Coating.* Compared with conventional multi-layer coatings, this PENTAX-original coating assures higher light transmittance and less reflection to deliver bright, high-contrast images that are free of flare and ghost images, even under demanding lighting conditions including backlight.

* HD stands for High Definition.

4. Quick-Shift Focus System
This PENTAX-developed system allows for flawless, delay-free switching from autofocus to manual-focus operation, after the subject is captured in focus by the camera’s AF system.

5. Weather-resistant construction
This lens features a dependable weather-resistant construction with eight sealing parts to effectively prevent the intrusion of water into the lens interior. Paired with a weather-resistant PENTAX digital SLR camera body, it creates a durable, dependable digital imaging system that performs superbly in demanding shooting settings — even in rain or mist, or in locations prone to water splashing or spray.

6. Other features
SP (Super Protect) Coating applied to the front surface of the lens to effectively repel water and grease

Rounded diaphragm to produce a smooth, beautiful bokeh (defocus) effect, while minimising the streaking effect of point light sources

Built-in DC motor to assure smooth, quiet, high-speed autofocus operation

Note: Designs and specifications are subject to change without notice.
