canon 600mm f5.6 lens patent 300x191 - EF 600 f/5.6 DO Patent

We’ve seen patents for DO lenses before. There are 300mm, 400m and 600mm DO patents.

Take a peak at some of the other lens patents Canon has filed. There was even one for a Zoom fisheye, though it’s different than what actually reached market.
