• intros：{"brand_intro":"适马（Sigma）成立于1961年，是日本知名的独立镜头制造商，以高性价比和创新光学设计著称。适马拥有自己的镜头生产线和光学研发中心，其Art系列镜头广受好评。TC-1401是适马为自家SA卡口和兼容卡口（佳能EF、尼康F、索尼E等）设计的1.4x增距镜。适马注重\"物超所值\"理念，在保证画质的前提下提供更具竞争力的价格。","product_intro":"适马TC-1401是一款专为适马Global Vision系列镜头（Art、Sports、Contemporary）设计的增距镜，可将焦距延长1.4倍。核心卖点在于其高性价比，价格仅为原厂产品的一半左右。光学结构采用3组6片设计，包含一枚低色散镜片。适用镜头包括适马70-200mm f/2.8 DG OS HSM Sports、150-600mm f/5-6.3 DG OS HSM Contemporary等。相比原厂，适马增距镜在兼容性上略有局限，但画质表现令人惊喜。","key_specs":{"倍率":"1.4x，光圈降低1档","光学结构":"3组6片，含1片低色散镜片","镀膜技术":"多层镀膜，减少眩光","卡口类型":"适马SA/佳能EF/尼康F/索尼E（需对应版本）","防护性能":"防尘防滴溅设计（部分版本）","重量":"约180克（佳能EF版本）"}}
