Problems with photography macro lenses

The so-called macro lens is a photographic lens with a very small object distance, such as Nikon's 105 macro. Its closest object distance is about 0.29 meters, which means the lens is almost close to the subject. This is one.

Second, the object-to-image ratio of a macro lens can be 1:1, which means that no matter how big the object is, it will also be how big it is on the CMOS. It is very suitable for photographing small objects, and the resulting photos can be enlarged.

These are incomparable to ordinary lenses.

Some ordinary lenses and zoom lenses also have macro functions, or you can connect a macro lens to achieve the purpose of macro photography, but the imaging effect is worse than that of professional macro lenses.
