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）。
