Macro lens parameters, what is the range of focal length of the macro lens

Just what you said in the two shots. In terms of imaging quality, it is definitely better than 17-85. But if you shoot macro, don't choose either, choose 100 micro.

Focal length range of macro lenses: The focal lengths of macro lenses are roughly divided into 60 focal lengths, 100 focal lengths (known as 100 micro) and 200 focal lengths. Taking a focal length of 200 as an example, the telephoto can stay away from insects (such as dragonflies and butterflies) without disturbing them, and complete the shooting.

In addition to shooting gemstones, watches, insects, etc., the macro lens can also shoot portraits, and portraits are also very sharp. Of course, if you want to shoot a bust, you need to adjust your macro lens to the non-macro end. If you're on the macro end, maybe you'll only be able to capture one big eye of the subject.

In order to accurately focus on subjects at very close distances, macro lenses are usually designed to be stretched longer so that the optical center is as far away from the sensor as possible, and the design of the lens group must also focus on controlling distortion and chromatic aberration at close range. Most macro lenses have a larger focal length than standard lenses, so they are not entirely suitable for general photography.

The focal length of the macro lens is relatively long, generally speaking, these macro lenses have some common characteristics, the focal length of the macro lens can be divided into 60 focal length, 100 focal length and 200 focal length, the reason why the focal length of the macro lens is so long, mainly to facilitate the shooting of some flowers and plants, and to shoot some insects and animals will not disturb them.

The biggest difference between a macro lens and a normal lens is that you can make the object you want to photograph larger, and you can even zoom in to 1:1, which means that you can take an image as large as the object being photographed. Macro lenses have a magnification of 1x or higher, and close-up shooting distances are closer.

Most focal lengths are larger than standard lenses, and macro lenses have a super high resolution and can capture objects very clearly, so the picture looks realistic. However, if you are shooting portraits, it is recommended that you do not choose a macro lens, because it is too clear, so even the pores can be seen clearly.

The main function of a macro lens is to shoot macro** and even the patterns on a butterfly's wings. In fact, the macro lens can also be used to shoot portrait works, and the clarity, contrast and saturation of the lens are also quite good, but the picture shot by the macro lens will be more "sharp", especially some more traditional close-up portrait lenses, which can present a lot of details.

Introduction: With the development of digital technology, digital has been integrated into us. A macro lens is a special lens used for macro photography, mainly used to photograph very small objects, such as flowers and insects.

In order to focus correctly even on very close subjects, macro lenses are usually designed to be stretched longer so that the optical center is as far away from the sensor as possible, and the design of the lens group must also focus on the lower possible distance'Control of distortion and color aberration.

Most macro lenses have a focal length larger than a standard lens and can be classified as telescopic lenses, but they may not be as good as general telescope lenses in terms of optical design, so they are not fully suitable for general photography.

Structure

There are generally two types of macro photography lenses. One macro photographic lens adopts the structure of a built-in telescopic lens barrel, and the other adopts a structure that replaces the front and rear positions of the optical lens group in the lens. If you want to take a close-up shot, as long as the focus ring that has been rotated to the nearest focus place continues to rotate, the entire optical system of the lens can be moved forward synchronously with the built-in lens barrel, so that the image distance is increased and the purpose of close-up photography is achieved. The latter uses to change the front and back positions of the optical lens group in the lens to obtain a higher image magnification, so as to achieve the purpose of close-up shooting.
