Standard zoom lens covering most frequently-used range
This standard zoom lens accommodates the image circle of a full-frame image sensor, and covers focal lengths between 28mm wide angle to 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’s 36MP sensor. Its compact, lightweight design and excellent cost performance make this lens a perfect companion lens to the PENTAX K-1.
Excellent image resolution, complementing the PENTAX K-1 full-frame 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.
HD Coating to improve image description
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.
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.
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
