If 99% pass the test, I would conclude my chances of getting as good a lens are very high, even if not Linhof tested. (2) At what size enlargement does the Linhof lens show significant enhanced image (resolution, contrast, saturation, color fidelity) compared to a non-Linhof lens? If the differences are not apparent until the image is enlarged to 5 x 7 feet, I would see any need to buy the Linhof lens. (3) Is the technical data (MTF, etc.) the same for the Linhof and non-Linhof lenses? If so, there is less reason to buy the Linhof lens. (4) Since the Linhof-rejected lens passed the original lens manufacturer's quality control tests, this suggests that Linhof accepts lesser variation from optimum quality than the original manufacturer. How much is the variation at which the original manufacturer will allow the lens to pass its tests? If the accepted deviation is small enough, there is less reason to value Linhof's pass-fail criteria. (5) How much does the Linhof name help with respect to the resale of the lens? I wonder whether the price for a used Linhof lens would merge with that of a used Caltar. xxx xxx xxx xxx xxx xxx
