According to the Egami Blog, Canon has filed a patent for a CN-E 24-70mm f/2.8 L S lens.
The curious thing about this patent is that Canon already makes a CN-E 30-105 T2.8 L S lens. With so little to differentiate the lenses, one wonders whether the extra 5mm on the short end will be a huge selling point compared to the 30-105’s extra 30mm of focal length range on the long end. [Sean]
