[QUOTE="Bengt Nyman, post: 462357, member: 13692"] Yes, but testing every lens on every camera, though desirable, is impractical, as shown by DxO slowly but surely loosing their grip. I believe there is a better way. The resolution of an optical serial pair is most heavily influenced by the weakest link. (Zeiss 1964). If you know the resolution of a camera image sensor and the resolution of a lens compatible with that camera, there is a mathematical way to predict the approximate resolution of the serial pair. There is usually more variation from lens to lens and within the focusing accuracy than there is in doing the mathematical synthesis. That said, I think that both LenScore and LensTip are on the right track. I have been told that LenScore is working on a piece of user interface capable of answering most of your questions about camera and lens performance based on the performance of the two separate components.
