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.
Comparing the E-M1 to the D7100 at low ISOs gives a good impression of how it stacks up against a camera with a larger sensor. In terms of resolution, the E-M1 does well, though theshows the D7100 doing slightly better. Neither camera has an anti-aliasing filter, so predictably they both show a bit of moiré in our scene's , though the E-M1 displays considerably less. Bumping ISO up to 800 shows a bit of fine detail and lost, but overall the E-M1 is doing quite well as compared to the APS-C sensor.
At ISO 6400 thefalls victim to noise and noise suppression. A stop above that at ISO 12800 shows a and poor results above that at the E-M1's limit of . Compared to the , noise levels seem to be similar, with the Panasonic camera appearing to do less smoothing. More grain is present, but so is slightly more fine detail.
Raw noise levels look comparable to that of the, with perhaps more masking in the from the E-M1. Noise levels appear to be similar until , at which point the noise in the E-M1's images has a more coarse appearance.
