Pursues the \"character of the lens\" not only through numerical evaluation by test equipment but also by repeatedly evaluating image quality through actual shooting and feeding it back into the design.\u003c\/li\u003e\n\u003cli\u003eWhen shooting distant subjects, it provides clear, sharp, and highly resolved depictions. When shooting close-up with the aperture wide open, the in-focus plane is sharp, while the out-of-focus areas blur softly and smoothly, creating a depiction that makes the subject appear to float.\u003c\/li\u003e\n\u003cli\u003eThe exterior uses high-grade machined aluminum for the lens barrel, hood, and cap, with meticulous attention paid to the texture of the body.\u003c\/li\u003e\n\u003cli\u003eThe optical system uses four ED (Extra-low Dispersion) glass elements and one Super ED glass element, which provide high chromatic aberration reduction effects, minimizing color fringing not only in the in-focus plane but also in the bokeh.\u003c\/li\u003e\n\u003cli\u003eBy using a large-diameter concave meniscus lens, a biconvex glass-molded aspherical lens, and high-refractive index glass for the first element, it achieves a compact size despite being an ultra-wide-angle lens, realizing sharp image performance without flow at the periphery.\u003c\/li\u003e\n\u003cli\u003eEmploys the high-performance multi-coating \"HD Coating,\" which suppresses average reflectance in the visible light spectrum to approximately 50% or less compared to conventional coatings. This effectively suppresses the occurrence of ghosting and flare under harsh lighting conditions such as backlight.\u003c\/li\u003e\n\u003cli\u003eFeatures an electromagnetic diaphragm mechanism. When used with compatible digital SLR cameras, smooth aperture control is possible.\u003c\/li\u003e\n\u003cli\u003eIncorporates a weather-sealed construction to prevent water droplets from entering the lens.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eProduct Specifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFilter Diameter: 67mm\u003c\/li\u003e\n\u003cli\u003eMinimum Focusing Distance: 0.18m\u003c\/li\u003e\n\u003cli\u003eLens Construction: 8 groups, 11 elements\u003c\/li\u003e\n\u003cli\u003eAperture Blades: 8 blades (circular aperture)\u003c\/li\u003e\n\u003cli\u003eFocal Length (35mm equivalent): 21mm (32mm when mounted on a PENTAX APS-C size SLR camera)\u003c\/li\u003e\n\u003cli\u003eMaximum Magnification Ratio: 0.26x\u003c\/li\u003e\n\u003cli\u003eWeight: Approx. 416g\u003c\/li\u003e\n\u003cli\u003eMaximum Diameter x Length: Approx. 74mm x Approx. 89mm \u0026lt;Lens Hood Fixed\u0026gt;\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAccessories\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eLens Cap O-LW74A, Lens Mount Cap K, Lens Case P80-150\u003c\/p\u003e","brand":"CFJ","offers":[{"title":"Default Title","offer_id":54401309180197,"sku":"2447570104994","price":919.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1024\/5816\/3493\/files\/2447570104994-1-1.jpg?v=1793997003","url":"https:\/\/camera-factory-japan.com\/products\/used-pentax-hd-pentax-d-fa-21mm-f2-4ed-limited-dc-wr-silver","provider":"Camera Factory Japan","version":"1.0","type":"link"}
