Macro technology

In a popular language that people can easily understand, the close-up lens can be simply understood as a closed shading tube, and its correct installation position should be between the back of the lens and the lens interface of the SLR camera. At the same time, we should understand that this will increase the image distance of the camera, thus greatly reducing the object distance from the subject. The biggest advantage of this is that it can be used for close-range shooting and realize the desire of every ordinary person to take close-range macro photography.
