This allows for powerful shooting expressions that dramatically bring the subject closer.\u003c\/li\u003e\n\u003cli\u003eUtilizing the advantages of the \"RF mount's\" large diameter and short back focus, a large lens element is placed at the rear (camera side) of the lens group, achieving both high image quality from the center to the periphery and a compact, lightweight design.\u003c\/li\u003e\n\u003cli\u003eAdoption of optical materials with high refractive index and low dispersion reduces various aberrations that cause image quality degradation. The use of a 3-element cemented lens, which reduces the number of air-to-glass surfaces, and optimized coatings suppress the occurrence of ghosting.\u003c\/li\u003e\n\u003cli\u003eDustproof and moisture-resistant construction is adopted for the mount and operating parts.\u003c\/li\u003e\n\u003cli\u003eHigh durability and resistance to vibration and shock are achieved, considering the attachment of heavy super-telephoto lenses.\u003c\/li\u003e\n\u003cli\u003eHeat-shielding paint is used to suppress lens temperature rise by reflecting infrared rays contained in sunlight.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eProduct Specifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eLens configuration: 5 groups, 9 elements\u003c\/li\u003e\n\u003cli\u003eMaximum diameter × length: φ71.2 × 39.3mm\u003c\/li\u003e\n\u003cli\u003eWeight: Approx. 340g *For compatible models and details, please refer to the manufacturer's website.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CFJ","offers":[{"title":"Default Title","offer_id":53959225770277,"sku":"2443801822729","price":519.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1024\/5816\/3493\/files\/2443801822729-1-1.jpg?v=1793934666","url":"https:\/\/camera-factory-japan.com\/products\/canon-extender-rf2x-1","provider":"Camera Factory Japan","version":"1.0","type":"link"}
