Canon Firmware version 1.4 compared to Sony A7R IV

Xing Liu compares the eye AF on the Sony to the new Canon firmware.

Watching the video a few times, it's a little hard to tell which one really does a better job because the model (@annasarandi) seems to be at different distances for either camera with the Sony camera having Anna at a closer focus distance which is easier for the camera to perform eye detect.  However, the fact that it's difficult to tell which one does a better job is a good testament to how quickly Canon has essentially caught up to the latest and greatest Sony camera.

Xing commented in the comments that the hit rate between the two cameras is basically the same, leading to confirmation of the eye test (pun clearly intended) that the two cameras eye AF is pretty similar now.

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!
