也许现在大多数影楼摄影师都习惯了在拍摄时使用标准变焦镜头。虽然变焦镜头在使用时的灵活性是定焦镜头无法匹敌的,但是一支标准定焦镜头(也就是我们常说的“标头”)依然是值得推荐和拥有的。毕竟,50mm标准镜头无论在与APS-C画幅相机搭配时(焦距等效于75mm)还是在与全画幅相机搭配时(焦距没有改变,还是50mm),其焦距都是非常适合于人像摄影的。而且定焦镜头的画质要好过变焦镜头,特别是标头的口径至少比变焦镜头大1级。无论 Perhaps most studio photographers are accustomed to using the standard zoom lens when shooting. Although the zoom lens is not flexible enough to be used with a fixed-focus lens, a standard fixed-focus lens (which we often say “header”) is still recommended and available. After all, 50mm standard lenses are ideal for portraits regardless of whether they are used with an APS-C format camera (focal length equivalent to 75mm) or with a full frame camera (focal length is unchanged, or 50mm). And the quality of fixed-focus lens better than the zoom lens, especially the header diameter than the zoom lens at least one level. regardless
