Out of camera JPEGs
By F5.0 both lenses are more consistent across the frame. These shots show how the camera's JPEG engines cope with moiré. Both the Ricoh and Nikon have been re-processed from Raw in-camera to fine-tune white balance. This option isn't available in the Sigma (which also doesn't offer white balance fine tuning, so the white balance is slightly less precise).

Real-world comparison
These shots were taken moments apart, to show how the cameras behave outside the studio. The shots were both taken and F3.2 and Auto ISO, with exposure compensation applied on the Nikon to more closely match the Ricoh's exposure. The Nikon image has been re-processed in-camera from a Raw file with noise reduction turned off, to match the Ricoh's setting.
We didn't shoot the Sigma in this test as the studio shots (which are taken in more favorable lighting) show the performance would make the comparison meaningless.
