Floyd L. DavidsonI'm wondering if the lens manufacturer could measure the point spread function for its lenses and provide this information to image processing applications, so that these could calculate the optimal sharpening function.
Any good optical engineer could work it out, given the right equipment and a fairly fat check.
That's not a likely route for any but the most serious and well healed.
In other words, software would compensate (at least partially) for the weaknesses of a lens, as it is being done with vignetting or geometric distortions in cameras. -- Alfred Molon
