This paper describes a method for measuring and assessing the veiling glare of 35 mm camera lenses. It is a simplified version of our previous method which makes 54 measurements over the 24 mm X. 36 mm picture format, at all apertures [SPIE Proceedings 274-41 (1981), Opt. Eng. 21 343 (1982)1. In this case, measurements are made at only the following three positions in the 24 mm X 36 mm format, and at four apertures: along a diagonal, at the center and at ±0.9h, h being the maximum image height; at the maximum (full) aperture, the second maximum, medium, and minimum apertures. The criteria being that: if the maximum veiling glare value measured at the above three positions is not more than 1.5 %, it is very good; between 1.5 % and 3 %, good, provided that, in both cases, the ratio of the maximum to the minimum veiling glare value is not more than four; between 3 % and 6 %, poor, more than 6 %, very poor
