Ranging from wide angle to medium telephoto, it’s designed to accommodate the image circle of the large full-frame image sensor, incorporating state-of-the-art optics and high-performance optical elements. A standard zoom lens is a lens in which the focal length varies, unlike a prime or fixed lens. A zoom lens is one that maintain (or regains) focus even with focal length of the subject-matter changes. Zoom lenses, such as this, provide the user with a convenient, go-to lens of variable focal length. When mounted on the PENTAX K-1 camera body, it delivers high-resolution imaging power, making it an ideal everyday-use lens, suitable for a variety of scenes, from landscape to street photography to portraits.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eCovers the Most Frequently-Used Ranges\u003c\/b\u003e\u003c\/p\u003e\n\n\u003cp\u003eThis 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. \u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eExcellent Image Resolution\u003c\/b\u003e\u003c\/p\u003e\n\n\u003cp\u003eWith 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.
