What is a macro lens?

           Macro lens is a special lens used for macro photography, mainly for capturing very subtle objects such as flowers and insects. In order to accurately focus on subjects with extremely close intervals, macro lenses are usually designed to stretch longer to keep the optical center as far away from the photosensitive element as possible. At the same time, in the design of the lens group, attention must also be paid to controlling deformation and color difference at close intervals. Most macro lenses have a focal length greater than standard lenses and can be classified as telephoto lenses, but their optical design may not be as good as ordinary telephoto lenses, so they are not fully suitable for ordinary photography.

          Macro photography lens refers to a specialized photography lens that can be used for macro or close range photography without the need for proximity accessories such as a proximity lens, proximity ring, or proximity track skin cavity. 

            Macro photography lens is a camera lens specifically designed to capture small subjects or reproduce small images. This type of lens has a high resolution, minimal distortion and aberration, high contrast, and excellent color restoration. Macro photography lenses have excellent resolution during close-up shooting, and can maintain imaging quality throughout the entire focusing range without significant changes. Ordinary photography lenses are mainly used to capture objects within the usual focal length and cannot be directly used for close-up shots. Applying a regular photography lens for close-up shooting requires the installation of close-up accessories such as a close-up lens, a close-up ring, or a close-up skin cavity in front of the lens. However, after installing these accessories on a regular photography lens, it becomes in a "close-up" state and cannot quickly return to the regular photography state. In other words, the method of installing close-up accessories on a regular photography lens makes it difficult to alternate between close-up shooting and regular photography. The macro photography lens, on the other hand, is different. Its close-up does not rely on other close-up accessories, and all close-up operations are performed on the lens itself. It can connect and focus between close-up and infinity, allowing for quick adjustment from close-up to normal photography. This provides convenience for photographers to alternate between close-up and normal photography.
