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 examining 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.
