镜头是摄影师的眼睛,一只优质的镜头能将相机的性能发挥到淋漓尽致,同时也是照片品质的保障。很多摄影师在拥有几只变焦镜头、焦段的覆盖范围已不再是问题时,都往往会将目光移向大口径定焦镜头,最受人像摄影师欢迎的高性价比定焦镜头就要算是f/1.4口径的50mm标准镜头了。标准镜头的镜片数量少结构往往也比较简单,各种像差都非常小。在最大光圈下能获得细腻柔和的画面,随着光圈的缩小,锐度会逐步增加,可获得更加清晰的画质。一般情况下,标准镜头的光圈多用于景深的调整,但该镜头的光圈对于画质的调整也起着很大的作用。
The lens is the photographer’s eyes, a high-quality camera lens to maximize the performance of the performance, but also the protection of photo quality. Many photographers have a few zoom lenses, the focal length of coverage is no longer a problem, they tend to focus on the large-caliber fixed-focus lens, most portrait photographers welcomed the cost-effective fixed-focus lens should be considered f /1.4 caliber 50mm standard lens. The lens of the standard lens less structure is often relatively simple, all kinds of aberrations are very small. In the maximum aperture can get delicate and soft picture, with the aperture diminished, the sharpness will gradually increase, you can get a more clear picture quality. Under normal circumstances, the standard lens aperture for depth of field adjustment, but the lens aperture for the quality of the adjustment also plays a big role.
