|Introduction | Nikon D5000 vs Nikon D5100: An improved sensor | Nikon D5100 vs Nikon D7000: same sensor, same results | Nikon D5100 vs Canon EOS 600D, the dxomark comparison | Conclusion|
The Nikon D5100 replaces the D5000 in Nikon’s lineup; it finds its place right below the Nikon D7000, according to Nikon’s marketing the D90 is still positioned between the D5100 and the D7000, however the spec sheet and the performances of the D5100 make this hard to believe.
This is because the D5100 shares the same Sony 16 megapixels sensor as the D7000. The major difference between the two bodies being the AF: 11 points with 3D tracking for the D5100 (presumably the “old” MultiCam 1000 already used on the D90) versus the 39 points with 3D tracking now used on the D7000.
On a side note: according to Nikon’s marketing the D90 is still positioned between the D5100 and the D7000.
The Sony 16 Mpx sensor has always shown an impressive performance in its use, regardless of the brand of the body it may be in: the Pentax K5, the Nikon D7000 and the Sony Alpha 580 all have superb metrics in common, especially the in the Dynamic Range. We do of course, expect the same from the D5100.
But before comparing those same generation cameras, we will measure the improvements from one generation to another.
