Canon looking at 20x super-zooms for APS-C and full frame?

We found this application for what appears to be a 28-550mm 3.5-6.3 full frame zoom.

The other embodiments are for a 15-300 3.5-6.3  for APS-C users.

With tamron coming out with a 18-300 super zoom for APS-C - is Canon looking to update the rather oldish 18-200 EF-S?

As with all patent applications that we show, this is a patent application.  This illustrates to us what Canon is looking at in their research labs.  It may or may not become a patent, and may or may not even after that be used in a camera system. 

Japan Patent Application JP017-134302A

How to view Japan Patent applications.

Unfortunately, there's no direct way of linking to the patent application (sad!) however, this is the easiest process to view a japan patent or application.

  1. Go to the Japan Patent Office search page.
  2. If it's a patent application (they are usually in the format of YEAR+Number ie: 2017-011300) then type the patent application number into the second field down from the top where it says publication of patent application. 
  3. Click on search.
  4. Then click on the patent application number link, and there's the patent application!
