Ricoh has introduced the HD PENTAX-D FA FA 28-105mm f/3.5-5.6ED 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.

The lens will retail for £549 and will be available from April 2016.

Pentax FA 28-105mm f/3.5-5.6ED DC WR Key Features:


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.

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.

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 includingbacklight.


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.


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.


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
