Actually, in the old days <=mid-sixties' WA weren't exactly great performers. When you multiplied their faults x 2 + added the faults of the teleconverter you got rather soft pictures. But like a lot of the photographic rules we seem to be slaves to it doesn't much apply to today's equipment. Also, true WA, not retrofocus, protrude too far out the back of the mount to use a teleconverer.
