Q:Monitor camera parameters how to see

Aperture: the aperture installed in the back of the lens, the greater the aperture open, the greater the amount of light through the lens, the higher the clarity of the image; the smaller the aperture, the smaller the amount of light through the lens, the image clarity low. Usually with F (luminous flux) to represent. F = focal length (f) / light aperture. In the camera's technical indicators, we can often see 6mm / F1.4 such parameters, which indicates that the focal length of the lens is 6mm, luminous flux of 1.4, then we can easily calculate the aperture of 4.29mm. In the case of the same focal length f, F value is smaller, the greater the aperture, reach the CCD chip, the greater the luminous flux, the better the lens.

Is also the camera (class camera) system, from the lens center to the film or CCD and other imaging plane distance. Simply say that the focal length is the distance between the focus and the vertex of the mirror.
