If an object is moved through a short distance δp along the axis, then the corresponding image shift δp′ is related to the object movement by the longitudinal magnification (m). Succinctly,

in which m is the lateral magnification. The fact that the longitudinal magnification is equal to the square of the transverse magnification means that m is always positive; hence, if the object is moved from left to right, the image must also move from left to right. Also, if m is large, then m is very large, which explains why the depth of field (δp) of a microscope is extremely small. On the other hand, if m is small, less than one as in a camera, then m is very small, and all objects within a considerable range of distances (δp) appear substantially in focus.
