I own a 7D – love my 7D!. I can’t afford the $200K Sony F35. We shoot RED cameras. The cleanest image in zone plate testing is clearly the RED. Best at any price point. Least amount of aliasing. Cleanest plate. At the end of the day, real world images mean more than lab tests. And the person behind the camera makes the image, not the camera itself. But it is still good to be able to explain the differences between these cameras and the information recorded by their various sensors.
