Canon patent describing a solution to avoid degradation of image quality in systems featuring a translucent mirror.
The problem: when light goes through a pellicle mirror to the sensor, the tilted mirror produces a tilt in the focal plane. The Canon patent counters this by tilting the sensor. Will we ever see this technology in a Canon product that hits the market?
