近摄镜片本质上可以说是一个改进的放大镜。其使用方便快捷,类似UV镜一样拧在镜头前就可以了。近摄镜一般是依据50mm标准定焦镜头设计的,若用于变焦镜头,尤其是光圈比较小的变焦镜头,成像效果会明显下降。安装近摄镜后对焦距离只能在20-30厘米之间,根据构图需要调整光圈来调整拍摄距离。近摄镜分大小号,1号镜、2号镜适合拍摄类似玉兰花大小的景物,3号镜、4号镜适合拍摄花心、蜜蜂等小型昆虫。号数越高,可放大倍率越大,变形也越大。
A close-up lens is essentially an improved magnifying glass. Its easy to use, similar to the same UV lens screwed in front of the camera on it. Close-up lens is generally based on the standard 50mm fixed-focus lens design, if used for zoom lenses, especially smaller aperture zoom lens, imaging results will be significantly reduced. After installing the close-up lens focus distance can only be between 20-30 cm, according to composition need to adjust the aperture to adjust the shooting distance. Close-lens size points, 1 mirror, 2 mirror suitable for shooting similar magnolia flower size of the scene, 3 mirror, 4 mirror suitable for shooting Faeces, bees and other small insects. The higher the number, the greater the magnification, the greater the deformation.
