What is a macro lens What is a macro lens?

Simply put, "The lens is very close to the subject, but it can be focused, and the image is clear," this is a macro lens.

Look at the details you want to shoot, you can see the pixels in the phone screen, the stamens of flowers. Details such as the small print on the wine glass, the printed words on the headphones, etc., should be taken in macro shots.

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 often designed to stretch longer so that the optical center is as far away from the sensor as possible, and the lens group must also be designed with a focus on proximity.

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 photographic lenses, one is the structure of the macro photographic lens lens with a built-in telescopic lens barrel, and the other adopts the structure of changing the front and rear positions of the optical lens group in the lens. In the former, in ordinary photography, the photographer only needs to rotate the lens focus ring to achieve normal focusing, and if he wants to take a close-up shot, he only needs to continue to rotate the focus ring that has been rotated to the closest focus.

The entire optical system of the lens can be moved forward synchronously with the built-in lens barrel, so that the image distance can be increased to achieve the purpose of close-up shooting; 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.

OneThe subject is differentA macro lens is a special lens used for macro photography, mainly used to photograph very small objects, such as flowers and insects.

The perspective of the scenery represented by ordinary lenses is relatively close to the visual vision, and it is often used in photography Li Ku's creation. It is the most basic type of loose photographic lens of all lenses.

Second, the focal length is differentThe macro lens close-up does not rely on other close-up accessories, and all close-up operations are performed on the lens itself, and it can continuously focus from close-up to infinity, so that it can quickly adjust from close-up to normal photography.

The focal length of a normal lens is between 45-55 mm.

3. The proportion of focusing distance is differentMacro lenses can achieve a 1:4 focusing distance ratio.

The focusing ratio of a normal lens can only reach 1:1.

Fourth, the magnification ratio is differentMacro lenses should have a magnification ratio of 1:2 or even 1:1.

The magnification ratio of a normal lens can only reach about 1:3.

Fifth, the range of viewing angles is differentThe angle of view of the macro lens can be close to 0°.

The angle of view of a normal lens is generally 45° to 50°.

The sharpness of magnified shots is differentThe macro lens can magnify the shooting before the disturbance, and the subtle parts can be presented in detail.

The ** of ordinary lens magnification shooting will be blurry, and even pixels can be seen in the details.

With the continuous development of science and technology, its camera has gradually appeared in various families, and now the camera can be divided into macro lens and ordinary lens. So, what is a macro lens? And what are the differences between them?

Macro lens slippery introduction:

In fact, the shooting of macro lens makes us feel that we are pulling in the distance from the object, but in essence, the role of the lens is to magnify the object when shooting, so that the photographer can observe the subtle substances in the shooting.

The difference between a macro lens and a normal lens:

In the difference between a macro lens and an ordinary lens, you can actually understand some from the overview of macro lenses. First of all, the macro lens can magnify the photographic object according to the proportion, and the pixels of the shooting ** are still clear, but the ordinary lens will magnify the photographic object after getting it is blurry**, and it cannot magnify the photographed object as clearly as the macro lens.

Camera renderings.

In addition to the focus of the lens, the macro lens can also be used as a normal lens, and it is possible to focus infinitely. In addition, some professional macro lenses cannot be closed at infinity, but they will definitely have a larger magnification. In addition to the pixels of the object being photographed, the pixels of the peripheral environment of the captured image are also very different between macro lenses and ordinary lenses.

The above is what is a macro lens, and what is the difference between it and ordinary lenses, do you know all about these contents? If you want to know more, stay tuned.
