The effective focal length is nearly equal to the stated focal length of the lens (F), except in macro photography where the lens-to-object distance is comparable to the focal length. In this case, the absolute transverse magnification factor ( m ) ( m = S 2 / S 1 {\displaystyle m=S_{2}/S_{1}} ) must be taken into account:
Consider an idealised Gaussian optical system, with the image and the object in the same medium.Thus, for an object in focus, the distance between the lens and image plane , the distance between lens and the object , and the focal length are related by the thin-lens equation:

The original application called for placing the chart at a distance 26 times the focal length of the imaging lens used. The bars above and to the left are in sequence, separated by approximately the square root of two (12, 17, 24, etc.), while the bars below and to the left have the same separation but a different starting point (14, 20, 28, etc.)
If the lens is held at a distance from the object such that its front focal point is on the object being viewed, the relaxed eye (focused to infinity) can view the image with angular magnification = Here, is the focal length of the lens in centimeters. The constant 25 cm is an estimate of the "near point" distance of the eye—the closest ...
