◆Standard zoom lens with a highly practical focal range This is a standard zoom lens that covers the image circle of a 35mm full-size image sensor, and covers focal lengths from wide-angle to medium telephoto with a focal length of 28 to 105mm. By using the latest optical design and numerous high-performance lenses, various aberrations are well corrected and sufficient peripheral illumination is ensured. It fully demonstrates the capabilities of the Pentax 35mm full-frame single-lens reflex camera, and is capable of outputting ultra-high-definition images. It has a compact and lightweight design that is easy to carry, and has high cost performance, making it suitable as a regular lens.

◆High rendering performance compatible with 35mm full-frame digital single-lens reflex camera Lens configuration with 15 elements in 11 groups, 2 high-precision aspherical lenses and special low dispersion (ED) that is effective in reducing chromatic aberration The lens uses one piece of glass and one piece of extraordinary low dispersion glass to achieve clear depiction with suppressed spherical aberration and chromatic aberration. In addition, in order to accommodate large image sensors with high pixels, the optical design has high resolution that enables detailed depiction.

◆“HD Coating” that improves depiction performance We have adopted a unique high-performance multi-coating “HD Coating”. Compared to conventional multi-coatings, it has less reflection and higher transmittance, suppressing the occurrence of ghosts and flare under harsh lighting conditions such as backlighting, and achieving high contrast and clear depictions.

◆Quick-shift Focus System The camera uses a “Quick-shift Focus System” that allows manual focusing after autofocus is achieved without any switching operations. Masu.

◆Drip-proof structure The lens has a drip-proof structure with sealing applied to 8 locations throughout the lens to prevent water droplets from entering inside the lens. By combining it with our digital SLR camera body, which has a splash-proof construction, it improves reliability in rainy weather, fog, and locations exposed to splashing water.

◆ SP (Super Protect) coating is used on the front of the lens to resist dirt.

◆ 9 blades suppress light beams when shooting point light sources and create soft circular bokeh circular diaphragm

◆ Autofocus uses a DC motor that operates quickly, quietly and smoothly
