超廣角全片幅變焦鏡頭
Tamron 推出 12-20mm F2.8 Di III 超廣角全片幅變焦鏡頭，新品同時提供 Sony E 接環及 Nikon Z 接環版本，適用於無反相機系統。
12-20mm F2.8 Di III 型號代表鏡頭設計上的重要一步，此鏡頭目前是騰龍（Tamron）產品線中視角最廣的全片幅變焦鏡頭，設計提供廣達 12mm 的寬廣視野。其光學結構針對超廣角攝影的特定挑戰而設計，配備擴展式玻璃模鑄非球面鏡片（XGM）及另外三片玻璃模鑄鏡片，確保由畫面中心至邊角均保持清晰銳利。對於天文攝影師及低光環境拍攝者而言，恆定 F2.8 大光圈是關鍵功能，可帶來更明亮的觀景窗畫面及更短的曝光時間。
英文原文
The 12-20mm F2.8 Di III model represents a significant step in lens design, as it currently holds the title of the widest full-frame zoom lens in Tamron's lineup. The design offers a field of view that begins at an expansive 12mm. The optical construction is engineered to tackle the specific challenges of ultra-wide photography by incorporating specialized elements like an eXpanded Glass Molded Aspherical (XGM) lens and three additional glass-molded elements to ensure sharpness from the center to the far corners of the frame. For astrophotographers and low-light shooters, the fast and constant F2.8 aperture is a critical feature, as it allows for brighter viewfinder imagery and shorter exposure times.
