Optimized lens construction through a short flange back and the latest optical design that takes camera-side optical correction functions into account, achieving both high optical performance and miniaturization.\u003c\/li\u003e\n\u003cli\u003eTwo large-diameter aspherical lenses on the front contribute to the overall compactness and high optical performance of the lens. The use of five FLD glass elements, which have the same characteristics as fluorite, and their optimal arrangement effectively suppress the lateral chromatic aberration and axial chromatic aberration that are particularly problematic in ultra-wide-angle lenses.\u003c\/li\u003e\n\u003cli\u003eEnjoy uniform and sharp rendering from the center to the periphery of the image, as well as beautiful bokeh. In close-up shooting, it is possible to create a three-dimensional image by utilizing the background blur unique to F2.8. Since ghosting and flare are prone to occur when the sun enters the frame in ultra-wide-angle zooms, thorough countermeasures have been taken from the design stage. The Super Multi-Layer Coating ensures excellent backlight performance.\u003c\/li\u003e\n\u003cli\u003eA 72mm front filter can be attached. This makes it easier to use PL filters and ND filters, which are frequently used in ultra-wide-angle photography.\u003c\/li\u003e\n\u003cli\u003eA stepping motor is used for the AF actuator. The agile and quiet AF is ideal not only for still photography but also for video shooting.\u003c\/li\u003e\n\u003cli\u003ePolycarbonate \"TSC (Thermally Stable Composite),\" which has a thermal shrinkage rate close to that of aluminum, is used in appropriate places. This minimizes errors due to thermal shrinkage between metal parts and ensures stable performance even in environments with large temperature fluctuations.\u003c\/li\u003e\n\u003cli\u003eThe pursuit of external beauty is also due to the high manufacturing technology and strict quality control of SIGMA's Aizu factory. It is not just a convenient and compact zoom lens, but also meets expectations in terms of operability and quality as a shooting tool.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eProduct Specifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eLens Construction: 11 groups, 16 elements (5 FLD elements, 4 aspherical elements)\u003c\/li\u003e\n\u003cli\u003eAngle of View: 107.0°-75.4°\u003c\/li\u003e\n\u003cli\u003eNumber of Diaphragm Blades: 9 (rounded diaphragm)\u003c\/li\u003e\n\u003cli\u003eMinimum Aperture: F22\u003c\/li\u003e\n\u003cli\u003eMinimum Focusing Distance: 25cm\u003c\/li\u003e\n\u003cli\u003eMaximum Magnification Ratio: 1:5.6\u003c\/li\u003e\n\u003cli\u003eFilter Size: φ72mm\u003c\/li\u003e\n\u003cli\u003eMaximum Diameter × Length: φ77.2mm × 100.6mm\u003c\/li\u003e\n\u003cli\u003eWeight: 450g \u0026lt;with lens hood\u0026gt;\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAccessories\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePetal-type lens hood (LH756-01), Front cap (LCF-72 III), Rear cap (LCR II)\u003c\/p\u003e","brand":"CFJ","offers":[{"title":"Default Title","offer_id":54294407512357,"sku":"2449030178316","price":724.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1024\/5816\/3493\/files\/2449030178316-1-1.jpg?v=1793508378","url":"https:\/\/camera-factory-japan.com\/products\/used-sigma-16-28mm-f2-8-dg-dn-contemporary-for-l-mount-1","provider":"Camera Factory Japan","version":"1.0","type":"link"}
