The photos taken by Canon EOSR directly on the screen are blurred, but they are very clear with the viewfinder. Why? The settings have not changed.

There are two ways for a camera to take pictures: LCD and viewfinder (optical viewfinder and electronic viewfinder). ..... In essence, no matter which framing method is used to take photos, the applied technical principle is the same. So, theoretically, as long as the settings are unchanged, the photos taken should be in the same state ... at least there is no difference in definition.

However, the actual situation is that ... the photos taken on the screen (LCD viewing) are blurred, while the photos taken with the viewfinder are very clear ... The reason for this situation is the focus problem.

Whether it's screen framing or viewfinder framing, taking pictures involves a focusing problem ... Only by focusing accurately and solidly can we take clear pictures ... This is the basic technology of photography.

As for why the photos taken by this camera when viewed on the screen are not clear, the specific reason is not very clear ... because the phenomenon is simply described in the question, but there is no more detailed explanation ... Personally, it is more conducive to the stability of the camera to use the viewfinder, so the film is clearer. When using the screen to view the scene, the film will be blurred because the camera holds it in an unstable way. ...

The above situation is just speculation. The specific reasons need to be analyzed when shooting, which can further clarify the shooting parameters of the photos.
