Canon patent for 6-22mm f/1.4-1.8 lens for Powershot cameras with 1/1.7″ sensor

6-22mm
View Post

Canon patent describing an optical formula for a 6-22 mm f/1.4-1.8 lens for a 1/1.7″ sensor equipped camera. 6-22mm is 28-100mm equivalent on full-frame sensors.

The Canon PowerShot G3 X and Powershot S110 are equipped with a 1/1.7″ sensor (as other Canon Powershots), so I guess this patent is possibly referring to a future Powershot model.
