Testing for this in full detail will require shooting a series of proper LCC frames through an appropriate diffuser, which I don't have with me but will get to next week. We can then see the effect of using CornerFix and other similar methods on the files. I admire the tenacity of Barjohn in doing the above shots and I think they do show that there's an issue but I agree that it isn't a deal breaker - these things are surprisingly prevalent though of course they do tend to be worse with non-retrofocal designs where the rear element of the lens is so close to the sensor, like with Leica.
