Canon Powershot Patent - 3.6-255mm f/2.8-7 Lens with Built-in Extender




Egami discovered another new Canon patent for PowerShot cameras. It is a 3.6-255mm f/2.8-7 lens with a built-in extender, effectively giving it a 35mm equivalent of about 2000mm @ f/10.

The Canon Powershot SX70 HS is expected to be announced very soon. This patent is most probably related to the same type of technology which enables the camera to have a 100x zoom capability.
