A simplified test procedure was developed that uses only the 45° target orientation. The lenses under test are focused for a given frequency on-axis. The on-axis MTF curve is recorded in one azimuth position of the lens, and the off-axis MTF curves for one selected field angle are recorded in three azimuth positions, The results obtained on ten lenses, each of two different lens types, will be presented in comparison with the results of photographic resolution tests on the same lenses. The results obtained from MTF testing appear to give better differentiation of lenses at a lower cost.
