At ISO 400 the majority of the differences in detail have been masked by the noise reduction routines (though again, the Canon seems to have the edge here in terms of detail, especially in the center of the frame). Again it's interesting to note that the Z750's result still looks over-sharpened and over-contrasty, and how very different these two manufacturers' approach to noise reduction is. Although the EX-Z750 has measurably lower luminance noise, the per-channel (chroma) noise is worse, producing strong colored blotches in mid-tones and shadows, again not helped by the high default sharpening. Again, 'turning down' the default sharpness, saturation and contrast settings produces a more natural-looking result.
