{"product_id":"7artisans-50mm-f-11-leica-m-mount-lens","title":"7Artisans 七工匠 50mm F\/1.1 (Leica M-Mount) 鏡頭","description":"採用7片6組松納結構方案設計，其中兩片玻璃使用了折射率1.9以上高折射率光學玻璃，使鏡頭有著優異畫質的同時保持著極佳的便攜性。研發過程中，非常刻意的考慮到鏡頭場曲和像散對圖像焦外虛化的影響，反復校正了兩者之間的比重關係，成像表現有著豐富的可玩性，在全開F1.1光圈時焦內細膩焦外奔放，收到F1.4之後能夠獲得二線性輕微，非常柔美的散景。對球差和慧差的反復校正，使得彌散斑在超大光圈鏡頭中控制的非常出色，焦點上的對比度銳度表現良好。","brand":"7Artisans 七工匠","offers":[{"title":"黑#000000","offer_id":45274706182322,"sku":"12194181","price":2950.0,"currency_code":"HKD","in_stock":true},{"title":"銀#c0c0c0","offer_id":45274706477234,"sku":"12194236","price":2950.0,"currency_code":"HKD","in_stock":true}],"url":"https:\/\/uat.elecboy.com.hk\/products\/7artisans-50mm-f-11-leica-m-mount-lens","provider":"ElecBoy UAT","version":"1.0","type":"link"}
