Assuming the effective aperture diaphragm is d, the relationship due to light refraction, the effective aperture of the lens actually is D, is greater than d, and the ratio of the focal length f D is defined relative to the aperture A, i.e., the relative aperture A = D / f, lens decision is proportional to the square of the relative aperture imaging illumination, like illumination and lens, with the general habit F = f / D, that is the reciprocal of the relative optical path to represent the size of the lens aperture. F value is smaller, the larger the aperture, the luminous flux reaches the CCD chip is larger. Therefore, in the case of the same focal length f, F value becomes smaller, the better the lens.4. lens focal length
