Our latest test scene is designed to simulate both daylight and low-light shooting. Pressing the 'lighting' buttons at the top of the widget allows you to switch between the two. The daylight scene is shot with manually set white balance, but the camera is left in its Auto setting for the low-light tests.
The Canon EOS 70D's low ISO JPEG output looks similar to the D7100's (the apparent difference in size is due to the greater resolution of the D7100). The 70D'sare slightly punchier, and the Nikon's lack of anti-aliasing filter shows up in the form of on close inspection. By the 70D's resolution of fine detail looks slightly sharper as the D7100 appears to have applied more noise reduction. The Canon seems to apply more sharpening, as seen in the 'crunchy' tone transitions in the . At the very top of the range things look quite noisy for both cameras, though the D7100 renders the better, though when scaled to , there's little difference.
Looking at Raw output from both cameras atshows a bit more fine detail from the D7100, though it's accompanied by some moiré and false color as seen in the man's sleeve in (also in the 70D's image, though not as prominently). Up at ISO 6400 in Raw mode the 70D seems to be showing up more than the D7100 - even when .
The rather clumsy sharpening we identified in our real-world shooting is clearly evident if you compare- even using our generic sharpening regime, the processed Raw file shows much more fine detail. This continues to be true, even at , though is a little exaggerated because we have noise reduction minimized in the Raw conversion.
