Product details

Lenses are mainly divided into zoom and prime focus, as well as magnification.

Zoom lenses, which we've just tried out, are lenses with variable focal length, which means you can push and pull. And then you have a prime lens, which is one focal length, one focal segment, or one Angle of view.

There are obvious differences in the appearance of the lens. Prime lenses have only a focus ring (which controls sharpness, described later), while zoom lenses have two rings, a focus ring (which controls sharpness) and a zoom ring (which controls Angle of view, i.e. push and pull).

Prime focus lens

Prime lens is easy to classify because of its fixed focal length:

Wide-angle lens: Generally, a lens less than 35mm is a wide-angle lens, and a lens less than 28mm is an ultra-wide-angle lens. Wide-angle lens has a wide viewing Angle, strong depth and deformation of the scene. It is more suitable for taking pictures of large scenes, such as buildings and gatherings.

Medium focus lens: Generally between 36mm and 134mm lens for medium focus lens. The medium lens is close to the normal human Angle of view and perspective, the scene deformation is small, suitable for shooting portrait, scenery, tourism souvenir photos.

Telephoto lens: Generally higher than 135mm lens is telephoto lens, also known as telephoto lens. The super telephoto lens is larger than 300mm. The telephoto lens has a small Angle of view, weak sense of perspective, and small deformation of the scene. It is suitable for shooting inaccessible things, such as wild animals, stage, etc. It can also use the function of the telephoto lens to dim the background to shoot the portrait.

Zoom lenses are difficult to generalize about because of their varying focus segments. It can also be called a wide-angle zoom lens or a medium-length zoom lens, assuming that its focal segment varies between one or two segments of wide-angle, medium-length zoom lens and so on. The most important part of a camera, the camera lens is the most important part of a camera

Because its quality directly affects the quality of imaging. At the same time, the lens is one of the most important criteria to classify the type and grade of the camera. Generally speaking, cameras can be divided into professional cameras, quasi-professional cameras and ordinary cameras according to the lens. Both traditional film cameras and digital cameras can be applied to this division. Lenses can be divided into zoom and prime focus. Professional cameras are also called SLRS, while full lenses should be called single-lens reflective cameras. The unique design of the reflectors and prisms of these cameras allows the photographer to view the image through the lens directly from the viewfinder. When light passes through the lens of the camera and reaches the reflector, it refracts to the focus screen above and forms an image. Through the eyepiece and pentapprism, the photographer can see the scene outside the picture window. When shooting, when the shutter button is pressed, the mirror will spring up, and the shutter curtain in front of it will be opened at the same time. The light (image) through the lens will be projected onto the sensitive component (film in traditional cameras, CCD or CMOS in digital cameras) to sensize it. Then the mirror will be restored immediately and the image can be seen in the picture window again. The lens of a professional camera can be removed completely and replaced with another lens to obtain a different shooting effect. Professional cameras have a wide variety of lenses, and their prices range from thousands to tens of thousands of yuan. Many lenses are even more expensive than the body. The various functions and indicators of the body must depend on the excellent optical lens to complete. Through the image conversion of the lens group in the lens to achieve the best effect of the current lens for the focus segment. How to choose a variety of camera lenses. To judge what lens you should buy the most by looking at the kind of shooting and route you are good at, do not blindly buy, causing the repetition of the focus segment.
