At ISO 400 the difference between Canon's fairly subtle and Casio's sledgehammer approach to noise reduction has widened the gap significantly. There's more detail in the A620 image, yet despite the Z750's heavier noise reduction it still looks noisy - with nasty blotches in all areas of solid color. Few small sensor compacts perform that well at ISO 400, but the A620 is amongst the better.

Note: as mentioned previously, the Casio shots were taken with the original firmware, we are assured that the default saturation is lower if you use the latest firmware, so the results won't look quite so over-blown, color-wise.
