Here is an inetersting Canon patent for a 100-40mm lens.

Canon Patent Application 2020-027156 (Japan) discusses optical formulas for a 100-400mm f/5.5-7.1 lens. The interesting fact is that this 100-400mm f/5.5-7.1 is for APS-C cameras. For the EOS-M system? We think rather not but it is possible. For sure it seems to be consumer lens.

  • Focal length:        119.97 218.00 360.96  
  • F-Number:             5.50   6.50   7.10  
  • Half angle of view:  6.50   3.59   2.17  
  • Image height:         13.66  13.66  13.66  
  • Total lens length:   179.62 192.93 233.56  
  • BF:                   15.03  15.03  15.04

Might this Canon patent application lead to a product that will actually hit the shelves? We’ve not made up our mind so far.

Canon patent application 2020-012922 (Japan) discusses optical formulas of what might become a future kit lens for the Canon EOS R full frame mirrorless system. The patent literature discusses formulas for two 17-70mm and a 16-60mm lens, and for both the EF and the RF mount. We think the RF mount lens is the one to have an eye on. The discussed lenses:

Canon EF mount:

  • Focal length 17.40 35.00 68.00  
  • F-number 3.33 4.09 5.88  
  • Half-field angle (degree) 51.19 31.72 17.65  
  • Image height 21.64 21.64 21.64  
  • Total lens length 168.42 153.33 168.42  
  • BF 38.32 53.44 84.11  
  • Focal length 16.30 35.00 60.00  
  • F-number 3.31 4.22 5.88  
  • Half angle of view (degrees) 53.01 31.72 19.83  
  • Image height 21.64 21.64 21.64  
  • Total lens length 68.46 153.33 168.42  
  • BF 38.35 56.15 83.82 

Canon RF mount:

  • Focal length 17.40 34.99 67.97  
  • F-number 3.31 4.12 5.88  
  • Half angle of view (degrees) 51.20 31.73 17.66  
  • Image height 21.64 21.64 21.64  
  • Total lens length 168.41 154.99 168.39  
  • BF 8.36 52.48 81.91

Canon Patent: IBIS Might Come To The Canon EOS M and PowerShot Lineup Too

We have no doubts that Canon will feature IBIS (In Body Image Stabilisation) on future cameras, given the remarkable collection of patent applications dealing with it and the fact that a Canon exec told the world about. And it’s very likely that the first Canon camera to feature it will be mirrorless.

Never the less, Canon patent application 2019-219650 (Japan) discusses how to feature IBIS on what seem to clearly be cameras in the Canon EOS M and Canon PowerShot lineup. So, IBIS coming to the m ore entry level oriented Canon cameras? Maybe not soon, but maybe sometime.

And yet another Canon patent application for yet another RF lens.

Canon patent application discusses the optical formula for an RF 135mm f/1.4L USM for the Canon EOS R full frame mirrorless system.

  • Focal length: 131.00mm
  • F-Number: 1.41
  • Half angle of view: 9.38°
  • Image height: 21.64mm
  • Total lens length:  182.28mm
  • BF: 13.87mm

We think this Canon patent application has a good chance to hit the market. In other words: we might see such a lens sooner or later.
