My point was simply that Canon hasn\'t made significant progress in sensor sensitivity.. they just made a full frame 20D sensor, and made it 1 stop better.. I\'d have hoped for more over the course of 4 years.
That is significant progress. One stop means an ability to work in half as much light. Don\'t cite Nikon. Nikon abandoned full frame and high iso, relied on noise-reduction to pretend it could compete, realised it had made a mistake, and then 2 years after the 5D produced a sensor that was as sensitive as Canon\'s best, but less detailed. The D700\'s light sensitivity isn\'t significantly better than the 1Ds3\'s, and it\'s only 12 megapixels, not 21. Nikon\'s progress seemed rapid only because it was so far behind. Improving on current sensors is harder than improving on the previous generations because the curve is getting closer and closer to the physical limits. Each successive stop of improvement is harder and harder to achieve. A one stop improvement over the 20D sensor is a great achievement. Don\'t be fooled by in-camera noise reduction.
