Can SLR zoom in and out like mobile phone shooting?

When shooting, if the SLR camera uses a zoom lens, the zoom ring of the lens can be rotated to change the imaging size of the subject without changing the shooting distance; If a SLR camera uses a fixed-focus lens, the imaging size of the subject can only be changed by changing the shooting distance.
