Canon applies for a couple of 1" sensor lens patents

Canon over several patent applications has applied for a lot of lenses for the 1" sensor.  These could be for surveillance or other purposes or some future powershot designs.

Canon Patent Application 2020-030252

This patent application discusses a 9-85mm F2.8-5.6 lens (equivalent focal of 24-233mm) with a 15mm (40mm) Macro function. The 9-85mm optical design is shown above.

Focal length      9.06  36.44 85.80 15.11  
F-number          2.88   4.14  5.47  5.47  
Angle of view    36.50  12.22  5.25  5.25  
Image height      6.71   7.89  7.89  7.89  
lens length      67.10  73.92 85.77 85.77  
BF                7.96   8.74 20.67 17.24  
Magnification    -0.00  -0.00 -0.00 -1.70  

It has another embodiment that is even more impressive as it's a 9-120mm or equivalent focal of 24-330mm) with again, a 40mm macro function.

Focal length      9.06  45.00 120.10  15.66  
F / No.           2.86   4.25   5.77   5.77  
Angle of view    36.50   9.94   3.76   3.76  
Image height      6.71   7.89   7.89   7.89  
lens length      87.71  92.89 107.94 107.94  
BF                7.33   8.94  21.68  15.00  
Magnification    -0.00  -0.00  -0.00  -1.70 

Canon Patent Application 2020-030250

This next patent application appears to identify a much simpler lens design. Most likely it allows it to be far more compact in nature.

The lens described in the patent application is a 9-42mm F2.8-F7.0 lens, which is 24mm-115mm equivalent focal length

An example embodiment is shown below;

focal length       9.06  18.00  42.65  
F-number           2.84   3.85   7.06  
Angle of view     35.66  23.67  10.48  
Image height       6.50   7.89   7.89  
Total lens length 77.00  66.08  79.54
