The difference between 15x macro and 20x macro

The magnification is different.

There are also different sharpness and different focusing distances. The magnification of 15 macro is 15 times, and the image quality is smaller when viewing objects. The magnification of 20 macro is 20 times, and the image quality is larger when viewing objects. Objects shot at 15 macro are less sharp than objects shot at 20 macro. The clarity of objects shot at 20 macro is higher than the clarity of objects shot at 15 macro. The focusing distance required for 15 macro is longer than that for 20 macro. The focusing distance required for 20 macro is shorter than that required for 15 macro.

The macro lens has a super close focusing distance. The macro lens can accurately focus when it is relatively close to the subject, while other lenses cannot achieve accurate focus when it is relatively close to the subject. A macro photography lens is a special photography lens that can be used for macro or close-up photography without installing close-up accessories such as a close-up lens, a close-up adapter, or a close-up rail. , in order to focus accurately, you need to install a close-up lens or a close-up orbital cavity. A macro lens can also be used as a normal lens and can achieve infinity focus. In addition, some professional macro lenses cannot achieve focus even at infinity, but they will definitely have greater magnification. In addition to the difference in the pixels of the objects captured between macro lenses and ordinary lenses, there are also great differences in the pixels of the surrounding environment of the captured images. All in all, macro lenses are better at photographing tiny objects than ordinary lenses. After all, the design of macro lenses also pays more attention to close focus imaging, while ordinary lenses have no related design.
