Nikon D5100 DxOMark ReviewThursday April 28 2011 Sensor Review
The biggest competitor the D5100 will have on the shelves will be the recently launched Canon EOS 600D. Both are at the same price point. On the Use Case scores however, the balance tips clearly in favor of the D5100.
On the latest testings D5100 seems better in every measure. The Dynamic Range being one of the most important differences, especially at low ISO settings: with more than 2 stops difference at ISO 100 there’s a really huge advantage for the D5100.
Though the other metrics also show a D5100 superior to the EOS 600D the difference is not as important on the SNR graph.
