Camera body: main functions and selection criteria

The camera consists of two main components. These are the camera body and the lens. It is the first element that concerns us in this article. The camera body plays a number of important roles. For example, it enables the light signal to be captured and the data to be processed.

What are the main functions of a camera body

The camera body, one of the two most important parts of the camera, has several roles and functions. It is the camera’s darkroom into which the light signal enters and is converted by its second lens. Its functions are subordinated to its different parts. These are: the mirror, which is a device for reflecting the visible image back to the viewfinder through the lens and a frosted area; the prism, also known as a penta prism, which is a small five-sided glass block. The last part is the shutter, which is the mechanism that allows light to pass through for a given time to impress the sensor. This part of the camera is also the support for the whole electronic system that determines the ISO sensitivity, the aperture, the shutter speed and the light measurement mode. Finally, it has a function that can sometimes integrate a built-in flash or can accommodate an external flash.

Selection criteria

 

A good camera body is the first element that should undoubtedly contribute to the choice of a camera. A bad camera body has a big impact on your camera. It is therefore necessary to check if the camera body is better, efficient before making any choice. The choice of camera body is essentially leaning towards the SLR. So a good camera depends on the SLR. To choose an SLR that meets your needs and expectations, look at the price, the optical equipment that can be replaced by a compatible camera if you have a quality lens. The viewfinder and ergonomics are other essential criteria. As far as ergonomics are concerned, it is advisable to choose the camera that is most comfortable to use after trying it out, as the functions vary.
