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-use lens for this new 35mm full-frame digital SLR camera.
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 optimizing 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 a perfect regular lens for the PENTAX K-1.
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 is designed to assure ample resolving power for the large, high-pixel image sensor, it produces well-defined, fine-detailed images.
The lens is treated with 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 free of flare and ghost images, even under demanding lighting conditions such as backlight.
* HD stands for High Definition.
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.
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.
・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 minimizing the streaking effect of point light sources.
・Built-in DC motor to assure smooth, quiet, high-speed autofocus operation
