设计

随着广角不断加大,对单反相机取景器的控制要求也在提高,这意味着后焦距要比焦距大的多,焦点后移设计被称为Distagon,是最佳选择。

功能

几乎毫无失真的光学特性

非凡的视角是创作最佳影像效果的根本。卡尔蔡司制造的各种焦段的单反相机镜头都可以胜任任何角度的拍摄。光学失真会破坏影像的平直度,原因是因部分光线不能经过图像中心,从而在影像边缘形成弯曲。卡尔蔡司所有焦段的镜头,通过复杂的光学设计和精细制作,无论在光线偏差和影像变形上都得到了精密矫正。

对杂光的抑制

丰富并充满活力的颜色是至关重要的,它会使一幅图片产生持久的美。但是当杂散光侵入镜头时,就会导致一个干净的图像,产生明显的阴影区。图像对比度会降低、沉闷和缺乏层次。我们通过各种复杂的技术,可以避免镜头产生杂散光。例如,我们所有的镜头都涂有著名的卡尔蔡司防反射复合膜涂层。此外,还使用特殊涂料涂布在所有镜片边缘以确保对杂光的阻止。

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。

出色的图像质量

卡尔蔡司镜头可以为您提供最高标准、可靠的、清晰及鲜明锐利的图像。拥有几乎为零的几何失真度,确保精确再现影像,特别是对拍摄要求极高的建筑和工业题材。

精确的手动对焦

手动对焦镜头是通过你的手指旋转调焦环这样一个良好的人机结合过程,完成对影像的捕捉。卡尔蔡司镜头拥有很长的调焦行程可以完成精确聚焦。影像的任何细微变化都可以立即在取景器上体现。高度精密的调焦结构使得调焦过程非常平稳,无论是在单反相机还是在平视取景相机上,制作精密的调焦环和清晰的蚀刻标示均可使手动对焦变得唾手可得。

The inner glow that is never extinguished

Hans Strand has earned a reputation as the most ‘poetic’ of landscape photographers. His images are works of art. And yet the 56-year-old, who has won numerous international awards, came to professional photography rather late in life. In this interview he discusses his career path, visual language, ...
