ZEISS Loxia 2.4/85
便携、不显眼、强大——可好地描述蔡司 Loxia 2.4/85 远摄镜头。这是特别为无反光的索尼α系列高分辨率、全帧传感器使用七个透镜元件全新改造的光学设计。Loxia 2.4/85补充了蔡司Loxia产品系列在较短的远摄镜头部分的焦距。
除了轻巧、灵便、价格适中，蔡司Loxia 2.4/85远摄镜头还提供卓越的图像性能——包括全帧传感器的整个像场。无论是人物特写、街景或是风景拍摄，这款不显眼的镜头都可以助您掌握这些摄影方法。
卡尔蔡司Loxia镜头专为索尼α7系列相机而设计。这意味着：在您手中，现代微单相机的优点将与经典摄影手动对焦的创作潜力完美结合。
还有一点十分重要，卡尔蔡司Loxia镜头可以为您提供卓越品质影片拍摄所需的一切条件——例如卡尔蔡司独有的DeClick功能可使您对光圈进行无级调节。

准确的手动对焦
手动操作镜头意味着可以准确控制图像效果。人体工程学是其中关键。卡尔蔡司镜头的特点在于较大的旋转角度，由此可以实现精准对焦。变化将立刻呈现在取景器中。高品质调焦机制运行平稳、毫无跳跃感，可令您对调焦平面进行直观调整。以米与英尺为单位的精准刻度以及焦深刻度为手动对焦提供额外辅助。
DeClick功能
Loxia镜头的一大全新亮点在于您可使用附送的工具通过卡口表面的调整螺栓消除光圈锁止机制的“咔咔声”。由此可对在影片拍摄中由相机摇动所引起的意外亮度差异进行无极补偿。得益于独特的设计，这一功能同样适用于其他拍摄系统。
几乎毫无失真的光学特性
广阔的视野与非凡的视角——卡尔蔡司镜头为您开拓全新的创意空间。失真会破坏影像结构，如果直线未能经过图像中心，在照片中将呈现为曲线。通过在所有焦距下的复杂视觉设计，这一令人懊恼的问题在较大程度上获得解决。
高品质全金属边框
卡尔蔡司镜头具有卓越的品质与极高的保值性，确保数十年经久耐用。制作精良的全金属边框、手感极佳的金属对焦与光圈环以及坚韧的前卡口与镜头过滤器螺纹为您带来难忘的摄影体验。此外，卡口配备独特的密封环，可保护相机与镜头之间的接口。
卓越的兼容性
蔡司Loxia镜头适用于带有E卡口的无反光索尼阿尔法系列相机以及最高为全35 mm格式（24 x 36 mm）的传感器。使用蔡司Loxia镜头，光圈是手动预设的，从而启动了机械光圈的DeClick功能。因此，相机具有相应的自动曝光控制功能（A）和手动曝光控制功能（M）。

镜片空气接触面少的镜头，是蔡司的路德维希·贝尔特勒博士（Ludwig Bertele）于 1930 年研发的。这种镜头是当时速度最快的 35 mm 摄影镜头，其光圈为 1:1.5，由于有效地减少了杂散光，所以提供了高反差。镜头的名字取自其高速和高反差，同时也来自“sun”，即太阳一词，代表最高的亮度。这种先进镜头的光学设计基于基础型号，您一定会不断发现上述在正常和远摄范围方面的优势。
Sonnar 设计
由带有异常部分色散的特殊玻璃制成的镜头
