ts true that most patents never appear in production products.
In this case, however, the patent may already be included in the recently announced Canon EF Cine lenses. Those lenses were believed to be just modified versions of the existing EF lenses, but now, I am thiinkiing they may, in fact have the IQ improvements described in the patent.
I've read the patent and tried to compare it to the new EF cine lenses, but there is no detailed info about their construction. We may never know for sure, but there is a good possibility. however, its merely that I see nothing in the patent that would preclude it from already being incorporated in those lenses, and nothing I've found says it is in them.
If thats true, we will likely be seeing new versions coming out over the next two years or so.
