Also, if ultra-fast lenses are so "troublesome" for digital sensors, why is Sony releasing a new 50mm F/1.4?


Because fast F-stops enable us to use shallow depth of field? They're also nice for available light photography. But going a full stop faster, say, from 1.4 to 1.0, does not equal twice as much light being recorded on the sensor which was the point of this "debate".
