小而不凡|索尼发布大光圈定焦 G 大师镜头 FE 50mm F1.4 GM

2023-02-22
      2023 年 2 月 21 日,索尼(中国)有限公司正式发布了 G 大师系列全画幅大光圈定焦镜头 FE 50mm F1.4 GM(型号名:SEL50F14GM)。这是索尼第 72 支 E 卡口镜头,同时也是第 17 支 G 大师镜头。这支镜头的加入,丰富了 50mm 焦段的选择,是高画质与轻量化的理想结合。在使用 F1.4 光圈拍摄时,也可提供出色的影像画质,呈现 G 大师镜头的优异分辨率表现和唯美背景虚化效果。搭配索尼全画幅微单™ 机身,FE 50mm F1.4 GM 可轻松胜任人像、风光、婚礼和旅行等题材,满足照片与视频的双影像拍摄需求。

优异成像和唯美背景虚化
FE 50mm F1.4 GM 采用先进的光学设计,具备 11 枚叶片以实现圆形光圈,优化的球面像差设计,使镜头可呈现柔美、深邃的全画幅镜头散焦效果,并且可在最大光圈时保持优异的分辨率,呈现 G 大师镜头系列出色的影像画质。F1.4 大光圈所营造的梦幻般唯美背景虚化效果,可让被摄主体从周围环境中脱颖而出,适合多种题材拍摄。
FE 50mm F1.4 GM 内置 2 枚 XA(超级非球面)镜片,有效矫正镜头畸变和像差,1 枚 ED(低色散)玻璃镜片,抑制色差,在保持锐利成像的同时减少色散。XA 和 ED 镜片的设计组合使镜头在整个成像范围内呈现优异的分辨率。索尼原创的第二代纳米 AR 镀膜技术则可在逆光等拍摄环境下,有效抑制眩光。
此外,FE 50mm F1.4 GM 最近对焦距离仅为约 0.41 米,自动对焦时最大放大倍率约为 0.16 倍,出色的近摄性能可以同时满足照片和视频双影像拍摄的特写需求。

重量仅约 516g 轻量化高机动性设计
FE 50mm F1.4 GM 采用了索尼先进的光学设计技术,包括高精度研磨的 XA 镜片、高推力 XD 线性马达和新的紧凑型圆形光圈叶片,这些技术的加入,使镜头在保持大光圈和优异分辨率的同时实现轻量化,重量仅为约 516g,体积仅为约 80.6 mm(直径)x 96.0mm(长)。与之前同规格镜头相比,重量减轻了约 33%,体积则减少了约 15%。
镜头搭配同样轻量化设计的索尼微单™ 机身,用户可更灵活地进行照片和视频双影像拍摄。得益于出色的机动性和弱光拍摄性能,FE 50mm F1.4 GM 可轻松胜任人像、风光、婚礼和旅行等多种题材的拍摄。此外,紧凑的尺寸也使其成为配合稳定器和无人机拍摄时的优异之选。

快速、精准与可靠的自动对焦
FE 50mm F1.4 GM 快速、精准的自动对焦性能,让用户可更放心地专注于内容创作。自动对焦速度相比上一代同规格镜头快约 1.9 倍。镜头对焦组由高推力 XD 线性马达驱动,并采用了先进的控制算法以实现平稳、灵敏的对焦。搭配索尼微单™ 相机,在使用 F1.4 大光圈拍摄浅景深影像时,该镜头也能快速对焦并精准可靠地跟踪拍摄主体。
XD 线性马达和优化的控制算法提升了镜头响应性能,从而实现了精准、安静的自动对焦表现,以 120p 或者使用其他高帧率拍摄视频时,也能轻松对焦并跟踪主体。在单人拍摄或小型团队拍摄时,可靠的自动对焦能够显著提升创作效率和灵活性。FE 50mm F1.4 GM 采用新的技术来减少呼吸效应,以获得更好的影像效果。此外,该镜头也支持索尼微单™ 相机中的呼吸补偿功能。

专业的操控和可靠性
专业的操控设计有助于提高创作者的拍摄效率。FE 50mm F1.4 GM 具备线性响应手动对焦功能,当用户进行细微的手动对焦操作时,镜头可以实现快速、灵敏、精确及可重复的线性响应。作为 G 大师镜头系列的新产品,FE 50mm F1.4 GM 也搭载了首次出现在索尼定焦镜头上光圈锁定开关。此外,该镜头的滤镜口径为 67mm,可与 FE 24mm F1.4 GM 和 FE 35mm F1.4 GM 镜头共用同尺寸滤镜。
对焦锁定按钮和 AF/MF 切换拨杆,为用户提供了更多的拍摄便利性。两个镜身对焦锁定按钮可自定义为相机菜单中的其他功能,而 AF/MF 切换拨杆则可以在自动和手动对焦之间快速转换,以适应不断变化的拍摄条件。
FE 50mm F1.4 GM 的前组镜片采用氟化物涂层,可减少镜头表面沾染灰尘、油污和其他污染物,同时也更容易擦去附着在镜头表面的指纹,防尘防潮设计为户外等复杂拍摄环境提供了更高可靠性。这些新增功能让用户可以在不同的环境中放心的使用镜头进行拍摄。
