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.
Main 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. - Excellent image description, complementing the full-frame digital SLR camera performance
