What is the viewfinder and what the camera viewfinder does

The viewfinder is the part of the digital video camera that monitors the image through the eyepiece, and the eyepiece viewfinder of the current digital video camera has a black and white viewfinder and a color viewfinder.

But for professional-grade digital camcorders, it's a black and white viewfinder, because the black and white viewfinder is more conducive to the photographer to compose the shot correctly. Digital video camera viewfinder structure and its liquid crystal display.

Similarly, both use TFT liquid crystals, but the difference lies in the size and power consumption of the two.

The one that is separated from the lens is generally called the optical viewfinder, regardless of whether the lens of the camera is in focus or zoom, the framing of the optical viewfinder is unchanging, it works irrelevant to the lens, it just imitates the angle of view and focal length of the lens.

The viewfinder that passes through the lens is generally called a TTL viewfinder (mostly used in DSLR cameras, this viewfinder is usually equipped in more expensive digital cameras.

, it displays the image captured by the lens.

The viewfinder is a window through which you can observe the subject with your eyes when shooting. Its function is to judge whether to adjust the shooting elements (such as the size, distance, height, angle of view, depth of field, virtual and real, tone, light and shade, whether it is horizontal or deliberately tilted, the master-slave of the scene, collocation, foiling relationship, position in the image, composition, etc.) by observing the scene in the viewfinder.

Viewfinders are generally divided into two types: optical viewfinder and electronic viewfinder. Optical viewfinders are used to directly observe the condition of the scene through an optical lens, and are mostly used in single-lens reflex cameras. The electronic viewfinder displays the image collected by the lens in the viewfinder through a photoelectric signal, and is mostly used in card cameras.

Today's DSLRs and card cameras can also be viewed in real time via an LCD screen.

The viewfinder is the part of the camera that monitors the image through the eyepiece.

The main function of a camera's viewfinder is to compose the picture, that is, to determine the scope and layout of the picture. In addition, some viewfinders can also display the parameters of the air height shooting and the depth of field, etc., a good viewfinder can have a more intuitive understanding of the final effect, and it is convenient to shoot more perfectly.

The difference between a camera with a viewfinder and without a viewfinder is: different use, different image quality loss, and different variations.

First, the use is different.

1. The camera has a viewfinder: The camera has a viewfinder and can be used in a strong light environment.

2. The camera does not have a viewfinder: The camera without a viewfinder cannot be used in a strong light environment.

Second, the loss of image quality is different.

1. The camera has a viewfinder: the camera has a viewfinder and does not experience the loss of image quality in the photoelectric conversion process, and has better expressiveness of the details of the scene.

2. The camera has no viewfinder: The camera without a viewfinder experiences the loss of image quality in the photoelectric conversion process, and the expressiveness of the details of the scene is worse.

Third, the changes are different.

1. The camera has a viewfinder: The scene displayed by the camera with a viewfinder will change with the adjusted shooting parameters.

2. The camera does not have a viewfinder: The scene displayed by the camera without a viewfinder will not change with the adjusted shooting parameters.

The only difference is that a camera with a viewfinder is not affected by outdoor light when taking pictures, so it can frame the shot well at all timesCameras without a viewfinder will not be able to see the display clearly in very good outdoor lighting conditions, and will not be able to frame shots well. For example, at noon on a sunny day, you can't compose a picture without a viewfinder camera, you can only shoot blindly.

Cards generally do not have a viewfinder, and machines with telephoto upwards are generally equipped with a viewfinder, which is more accurate than the display screen, and is very important for photography enthusiasts who are looking for angles and image quality.

The viewfinder can be used in high-light environments, and the screen is often difficult to see in sunlight.

The holding method of using the viewfinder is conducive to the stability of the machine and is not easy to paste.

Flipping the LCD screen also has the advantage of being good for multi-angle framing, and it is especially useful for high and low angles.

I believe that this question is still more important. After all, digital cameras are different from film in terms of imaging, and I have two reasons, first, whether the nominal sensitivity of digital cameras is accurate is debatable, and second, whether you have enough experience. I think the advantages of digital cameras over film cameras are reflected on a large screen, and it is important to check and correct the effect of the shot.

In addition, the parameters of the camera are also displayed through that screen. If you've ever said optical viewfinders, most rangefinder viewfinders aren't very effective, but they do have some advantages in terms of power saving, and it's also a useful feature when it's hard to see the LCD screen in strong light. However, it will not affect the final imaging.

However, in order to ensure the effect, please give priority to the use of the LCD screen when conditions permit. When configuring a camera with an EVF viewfinder, please give preference to the EVF viewfinder :)

1. The function of the electronic viewfinder is to be used for digital cameras and digital video cameras to look at the scene they are shooting, that is, to take pictures. Power is required for operation, similar to an LCD display. Generally, the electronic viewfinder used in digital equipment is divided into black and white and color.

2. The electronic viewfinder is to put a miniature LCD inside the viewfinder, due to the obstruction of the fuselage and the blindfold, the external light cannot shine on this miniature. The sail finder is also more practical, this way of framing is not only cheaper, but also can be used in any ambient light. The electronic lens finder can display the whole picture of the object to be photographed, and can display shooting information such as the aperture and shutter speed of the car stove, but in addition, it can also display the camera menu, which is not possible with other viewfinders.
