Abstract

A 50mm f/2 camera lens has been circulated to approximately 9 different laboratories throughout the world together with a specification carefully defining test conditions for a set of MTF measurements. The paper described the test specification and the results of the measurements obtained from the different laboratories. It also presented the results of a computer analysis with attempts to establish quantitively the cause of differences between sets of results. In particular the results have been analysed with regard to mechanical misalignment, differences in choice of focal planes, normalisation errors, spatial frequency etc.
