Canon Patent Application: Zoom lens for 1" sensor sizes

This patent application is for a zoom lens from 24mm to 95mm equivalent focal length for a 1" sensor size.

It's good to note that this has slightly less range than the lens that is already in the G7X Mark II, already. However, this is a faster lens, starting at 1.6-2.6 versus the 1.8-2.8 of the existing lens.

The elements that Canon is looking to improve with this patent application is downsizing the entire lens and a thinning of the lens when it is retracted, while maintaining a high level of optical performance.

Focal length           9.06 16.51 30.07
F-number               1.65  2.30  2.47
Half angle of view    36.48 25.54 14.70 (degrees)
Image height           6.70  7.89  7.89
Total lens length     63.80 66.03 79.50
BF                     5.57  4.57  6.07
