目前,越来越多的影友开始采用镜头倒接的方法来拍摄微小物体,并且取得了不错的效果。我们应当承认这是一种比较实用的好方法,但也是一种“土”办法,因为镜头倒接后会出现自动光圈失灵、倒接环与镜头滤镜螺丝联接不够安全、难匹配遮光罩与滤光镜（当然有办法解决）等问题。尤其是一些相机在镜头倒接后内测光会失灵,这对正确曝光会造成很大麻烦。对此有影友通过＂计算＂,将各焦距段的放大倍率及曝光补偿公布于众,如＂28mm,曝光补偿3.5级;50mm,曝光补偿2级……＂（详见《中国摄影报》2002年5月 3日《变焦镜头倒
At present, more and more shadow friends began to use the method of shooting lenses to shoot tiny objects, and achieved good results. We should admit that this is a more practical and good method, but it is also a “native” approach because automatic lens failure occurs after the lens is inverted, and it is not safe enough to attach the lens to the lens filter screw. It is difficult to match the hood Filter (of course there are ways to solve) and other issues. In particular, some cameras fail to detect the internal light after the lens is inverted, which can cause a lot of trouble for the correct exposure. For this shadowy friends through the “calculation”, the focal length of the magnification and exposure compensation announced in public, such as “28mm, exposure compensation 3.5; 50mm, exposure compensation 2 ......” (See “China Photography Newspaper” May 3, 2002 "Zoom lens down
