The ELCAN 50/2 has much the same formula as 2 90mm lenses that Leitz produced. Dr. Mandler, one of the designers of this trio, states clearly that the 50mm lens is overstretched for that lens formula. This sounds peculiarly like what Erik just said about the new CV lens.
So you produce a lens somewhat wider (or faster) than what the lens formula can handle, and edges show aberrations. Nonetheless, the lens "works".
Here is the center 1/5 of an image I took a few days ago. Nothing wrong with this, except loss of detail in the extreme highlights.
