The new compact and lightweight HD PENTAX-D FA 28-105mm f/3.5-5.6ED DC WR lens provides the most frequently requested focal-length range for general photography, from wide angle to medium telephoto.
This versatile zoom lens is designed to cover the large full-frame sensor found in the new PENTAX K-1 camera, incorporating state-of-the-art optics and high-performance optical elements. When mounted on the K-1 camera body, it delivers high-resolution imaging power, and is an ideal every day-use lens for the new camera.
Main Features
1. Standard zoom lens covering most frequently-used range
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 aberrations. It delivers high-resolution images by optimizing the imaging power of the PENTAX K-1 camera's approximately 36.4 effective megapixels. Its compact, lightweight body and excellent cost performance make this lens a perfect companion lens to the PENTAX K-1.
2. Excellent image resolution, complementing the PENTAX K-1 full-frame digital SLR camera performance
With 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. The optics are designed to deliver ample resolving power for the large, high-pixel image sensor, producing well-defined, fine-detailed images.
3. HD Coating to improve image quality
This lens is treated with the high-grade, multi-layer HD (high-definition) 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 such as backlight.
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.
