I think you knew what he meant, Jostein. You're just funnin' him, right? <g> The single photon occupying the lens' axis is dead on, 90 degrees to the plane of the sensor, and by definition, all other ray paths out to the edge of the sensor must necessarily be at increasingly larger angles... > IMO, it's pretty obvious that a microlens has an acceptable angle of view. > Within which, the light will trigger the right response in the sensor. > Beyond which, the light will behave in a way that will cause problems.
