设计

Touit 2.8/12

随着广角不断增加,采用焦点后移设计的 Distagon 镜头也可成为非单反相机的最佳选择。Distagon 结构能让入射到数字传感器的光线倾斜角极小,且保证了非常均匀的亮度分布。

非球面镜头
用不规则局部散光特殊玻璃制造的镜头

功能

Touit 2.8/12

安静且非常流畅的自动对焦操作

自动对焦系统需要可超精准地移动特定镜组。 根据被移动镜片(镜组)的重量来选用不同类型的电机。Touit 镜头对焦系统的设计未对其光学部分造成影响,并能保证平稳且顺畅的自动对焦。

创新产品设计

卡尔·蔡司镜头从数千件参赛产品中脱颖而出,一举成为设计大奖的赢家。独特的新款产品设计基于一体化理念,且只针对主要功能部件。仅保留遮光罩,其余部件均被作为配件。金属镜身可确保高稳定性,而橡胶调焦圈则可实现精准手动对焦。简洁且经哑光处理的表面令镜头的光学和机械精度一目了然。这真可谓是操作性极佳且符合大众审美需求的创新产品设计。

 

非球面镜片设计

非球面镜片设计确保了影像可在整个调焦范围从中心到边缘均有锐利的图像。与普通镜头相比,使用非球面镜片可以减少或消除球面像差和其他光学像差。

浮动镜片设计

先进的摄影技术和高分辨率数字图像传感器对镜头的要求越来越高。由于各个焦段的卡尔·蔡司镜头均采用了现代浮动镜片补偿像差技术,故而可以保证提供高超的影像素质。这是一种通过改变镜头内各个镜片或镜组的轴向距离,局部调整镜片在调焦时向像差小的方向移动从而使光线偏差和影像变形得到精细矫正的技术。精密的机械设计与制造、复杂的镜片磨制和严密的安装工艺是实施浮动镜片设计的保障,而这几项工艺恰好是卡尔·蔡司的专长。

高解像度和高对比度

丰富且充满活力的色彩对创造出美轮美奂的影像至关重要。而如果有杂散光侵入镜头,则会导致在明亮的图像中出现特别明显的阴影,还会造成图像对比度下降 – 其结果是图像沉闷且缺乏层次感。我们会使用各种复杂的专业技术,抑制镜头内的杂散光,从而提供高分辨率和高对比度的图像。

卡尔蔡司防反射涂层

即使在非常不利的光线条件下,拥有卡尔·蔡司独有 T* 抗反射涂层镀膜的光学镜头依然可以拍摄出色彩艳丽明亮的图片。我们独创的真空镀膜技术,将一层极度稀薄而透明的物料,采用真空淀积的方法及精确控制厚度技术涂镀在镜头表面,可有效消除镜片的反射光。这一镀膜技术由卡尔·蔡司公司于二十世纪三十年代首次应用。
