I gotta say, I just love the fact, that they announced a super-35mm 4k version a couple of days ago. Now it makes sense to use the EF-mount - before it was a little bit rediculous in my opinion, with the camera starting as a m4/3 sensor-size. Time to drop the good old "Canon is just not feeling the wind of change", only this time it isn't Nikon who leaps further ahead of them but a completely new compeditor. Respect!
