Canon has filed a new optical formula for a 12-60mm f/2-4 lens. From the patent application we can understand that this optic is apperantly designed for 1.5″ sensor cameras.
Canon has the very popular PowerShot G1 X Mark II model. The high-end compact camera is priced for $649 at Amazon. The interesting part is that the cameras has a 12.8MP High-Sensitivity 1.5″ CMOS Sensor with a 12.5-65mm f/2-3.9 lens.
This patent is such and indicator that the company is developing a PowerShot G1 X Mark II successor. More details can be found below.
Canon 12-60mm f/2-4 lens patent might be for Powershot G1 X Mark III
Even there is a possibility that the Powershot G1 X Mark III may come with improved APS-C sensor. If the same kind of lens is in the works for a large 1.5-inch-type CMOS sensor, than we can expect the third model not to be in APS-c sizes.
