We’ve been told that Canon’s next L lens would be a prime. Most of the people I’ve talked to think that the EF 35mm f/1.4L will be the lens getting the update. There have been a lot of patents in the past for the optical formula, and recently a new one has appeared.

Patent Publication No. 2015-72370 (Google Translated)

Example 1

  • Focal length f = 35.47mm

We expect to see a new L lens some time in late summer or early fall and all the signs continue to point to a new 35L.
