Kevin,
I trust the crypto-racist, isolationist charge wasn't directed at me. My suspicion that the Chinese EDs might be EL copies didn't come from politics, but from the objective design, which is a bit unusual nowadays. Among the alphas only Swarovski uses one like it. Anyway, Nikon seems to have done worse for itself vis-a-vis the EL. If the rumors are true it got into legal trouble for coming too close to copying the patented EL focuser (and screwing it up), while ironically using an optical design totally different and IMO superior to the EL.
