The viewfinder of Canon ft camera turns black after the shutter is released.

1. The reason why Canon camera views the black screen in real time is that the battery is dead, the front cover is not open, and the imaging chip is faulty. The details are as follows: According to the relevant information, the battery of Canon camera is insufficient, and the camera contacts have oxidized dirt, which will cause the camera to fail to open the LCD screen, so it is necessary to check the battery and charge it in time.

2. For film SLR cameras, including Canon SLR, after pressing the shutter button, the reflector in the camera body cavity should be turned up first. At this time, the viewing frame will be covered by the reflector, which is black, and then the shutter of the focal plane will act to expose the film. This situation is normal. You can see better in the slow door.

3. In this case, first check the lens cover. (It's easy to forget the lens cover, including experienced photographers) and the shutter is stuck, so I won't go back after I get down.

4. When shooting in the studio, if the viewfinder appears black, there may be the following reasons: First, the ambient light is insufficient. Because the light in the studio may be dim, if the camera viewfinder does not manually turn on the automatic exposure or adjust the shutter speed, a black screen will appear.
