Abstract
A surveillance camera system includes a photographing lens system, and a camera body to which the photographing lens system is detachably attached. The camera body includes a color imaging device on which an image formed by the photographing lens system is formed. The correcting of aberrations is carried out in a photographing lens system so that the difference between (1) the in-focus position at which the maximum MTF characteristic in the visible light wavelength range of about 400 nm to 700 nm is obtained and (ii) the in-focus position at which the maximum MTF characteristic in the near-infrared light wavelength range of about 700 nm to 1000 nm is obtained is less than 10.mu.m.
