This enables powerful shooting expressions that magnify the subject.\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 high refractive index and low dispersion optical materials reduces various aberrations that cause image degradation. The use of a 3-element cemented lens, which reduces the number of air-to-glass surfaces, and optimized coating suppress 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: 4 groups, 7 elements\u003c\/li\u003e\n\u003cli\u003eMaximum diameter x length: φ71.2 x 20.3mm\u003c\/li\u003e\n\u003cli\u003eWeight: Approx. 225g *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":54401987248421,"sku":"2449240140868","price":489.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1024\/5816\/3493\/files\/2449240140868-1-1.jpg?v=1793999055","url":"https:\/\/camera-factory-japan.com\/products\/used-canon-extender-rf1-4x-11","provider":"Camera Factory Japan","version":"1.0","type":"link"}
