A patent showing a faster version of the EF-M 15-45mm has appeared in the form of three separate optical formulas.
- EF-M 15-45mm f/1.8-3.5
- EF-M 15-45mm f/2.0-4.0
- EF-M 15-45mm f/2.8-5.0
Canon News Summarizes:
It also looks like it may be the first canon lens patent application that I've seen that specifically mentions that distortion abberation control happens in camera versus being controlled by the lens.
This would tend to make more of a compact camera approach as the powershots do this already, however Canon M's do not.
As with all patent applications that we show, this is a patent application. This illustrates to us what Canon is looking at in their research labs. It may or may not become a patent, and may or may not even after that be used in a camera system.
