The cameras are assessed against expectations/aspirations at their level, otherwise professional level cameras would probably always score 5/5 while entry-level models would fairly very badly, when in fact they are ideally suited to their target audience.
As I have said elsewhere on this forum, the D7000 is an excellent camera, but it is £100 more expensive than the EOS 60D and it doesn’t have an articulated screen (which promotes shooting from creative angles) or the in-camera image rating which is very useful. The D7000 is also prone towards overexposure and the AF struggles more than the EOS 60D’s when light-levels drop.
As for the resolution scores, the D7000 sample we had in for this test failed to achieve quite the same result as the previous body we had in. I have to say the reproduction of the chart in the magazine hasn’t done the D7000 any favours here – but we always assess the score on-screen.
The noise graphs show the signal to noise ratio (SNR) for the JPEG files as this reflects what the manufacturers consider to be the ideal end result. Generally, a high value means there is a high signal and comparatively low noise – which is good. The D5100 and D7000 have the same sensor, which means that it is the processing that is responsible for the difference in their output and the SNR. The D5100 JPEGs appear to be processed to reveal more detail, which in turn means there is more noise – and a lower SNR.
