Image: 5D Mk III, EF 24-70f/2.8L II, 70mm 1/125 sec at f/2.8, ISO 25,600.
Low light photography like this was not even conceivable 10 years ago, now with only a candle and ambient night time light we can shoot at ISO 25,600 and have usable images, its really quit extraordinary.
When the image is downsized as in the top image, noise is virtually none existent, the 100% crop shows some noise, but this is still incredible performance for today's cameras.
This will be very helpful in low light performance and concert photography, not to mention a new form of portrait photography.
