Some photographers say that a full-frame camera has a shallower depth of field than a half-frame camera, right?

We often say that there are three main factors that affect the depth of field in photography: aperture, focal length and focusing distance (the distance between the camera and the subject).

Another factor that affects the depth of field is the area of the camera sensor CCD or CMOS. The larger the area, the smaller the depth of field (which is also one of the main reasons for the large depth of field of the card machine). Because the sensor area of a full-frame machine is larger than that of a half-frame machine, a photographer is right to say that the depth of field of a full-frame machine is shallower than that of a half-frame machine. It's just that this factor is difficult to control artificially in photography, so it is generally not mentioned when talking about depth of field.

I hope to adopt.
