This paper presents veiling-glare of current lenses of various types, wide angle, standard, telephoto and zoom lenses; introduces the effect of reflection in camera bodies; proposes criteria for the assessment of veiling-glare. Veiling-glare does not differ significantly with focal lengths of lenses but differs appreciably with manufacturers: less than 1 % to more than 10 %. The increase in veiling-glare due to reflection in a camera body differs with manufacturers: less than 1 % to several per cent. According to the result of comparison of the measured veiling-glare values with actual pictures taken by the lens-and-camera systems under test, the following criteria correspond very well to the actual photographic perfomance: veiling-glare of not more than 1.5 %, very good; between 1.5 % and 3 %, usually good; between 3 % and 6 %, usually poor; more than 6 %, poor.
