Abstract

MTF-based simplified test conditions and proposed criteria for the evaluation of the image quality of fixed focal length lenses and zoom lenses for 35 mm cameras are described. Measurements are made for white light, in the infinite conjugate plane, on-axis and at two 0.7 field (15 mm off-axis) positions, at full aperture and f/8. The focus is set at full aperture for best MTF response at 30 mm-1 on-axis. The lenses are evaluated by exam-ining the MTF responses at 10 mm-1 and 30 mm-1. Previously proposed conditions and criteria for fixed focal length lenses are also described for reference.
