{"product_id":"f0015771","title":"Used ZUNOW 50mm f\/1.1 Overhauled February 2026","description":"[Appearance]\nAppearance Rank: A\nThe exterior shows slight signs of use, and there are faint rust marks on the mount. Among used items of the same model, this unit is considered to be relatively clean.\n*Please check the photos.\n\n[Optics]\nOptical Rank: B\nLens Condition\n\nA few dust particles are visible inside the lens with the naked eye.\nA few faint traces of mold are visible on the front element when illuminated.\nThere is a faint haze on the front element, some internal parts, and the outer periphery, which will have almost no effect except in backlit conditions.\nA few scratches visible to the naked eye are present on the front element and internally.\n\n[Functionality]\nFunctionality Rank: B\nThere are some scuffs on the aperture blades, but they operate generally smoothly.\nThere are no other functional issues.\nThis item has been overhauled, but please consider it after reviewing the product description.\n\nDesigned in the 1950s, this lens may produce a whitish image due to flare and halo effects under strong light conditions when shot wide open (f\/1.1-1.5).\nThis is a characteristic rendering tendency of this lens.\n\nIf concerned, stopping down by one stop at a time will gradually improve the image, and around F2, the contrast will significantly improve.\n\nAdditionally, a faint haze may be observed on the middle element when exposed to strong light.\nThis is due to the volatilization of grease used in old lenses, which may cause reduced contrast in bright environments.\n\nFurthermore, the coatings of that era are not as strong as modern lenses, so flare tends to occur in backlit or strong sidelight conditions.\n\n*Due to the design with a significantly protruding rear element, there is a possibility of interference with the shutter curtain or sensor depending on the camera it is mounted on. Please check carefully when mounting.\n\n[Accessories]\nFront and rear caps\n\n[Serial]\n5257\n\n[Condition]\nRank: B1\n\n[Control Number]\nf0015771\n\nAs this is a used item, it is a one-of-a-kind product.\nIt is displayed and sold simultaneously in stores and on other websites, so even if it shows \"in stock\" on this site, it may already be sold.\nThank you for your understanding.","brand":"ZUNOW","offers":[{"title":"Default Title","offer_id":47805317218524,"sku":"f0015771","price":999800.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0765\/9896\/8540\/files\/260308-1-097.jpg?v=1774609404","url":"https:\/\/fivestarcamera.net\/en\/products\/f0015771","provider":"Five Star Camera | ファイブスターカメラ","version":"1.0","type":"link"}
