New Patent: Canon 3.6-255mm F2.8-7 w/ Built-in Extender for PowerShot

Canon recently filed a new patent for 3.6-255mm f/2.8-7 lens with built-in extender. This means that this lens can reach 2000mm f/10 when converted to 35mm. And, this new lens is designed for a PowerShot camera. Besides, Canon already filed a patent for 3.8-380mm f/2.3-7 lens, a 100x zoom lens patent for a PowerShot camera. The Canon PowerShot SX70 was supposed to be launched with a 100x optical zoom lens. All these patents are good signs that Canon will announce the PowerShot SX70 HS camera in the near future.
