Compared to...

Below you will find a studio comparison between the Sony DSC-S90 and the Canon PowerShot A520. We have included samples for the lowest and highest ISO settings for each camera (S90: ISO 80 and 400, A520: ISO 50 and 400).

Studio scene comparison (Sony DSC-S90 @ ISO 80, Canon A520 @ ISO 50)

  • Sony DSC-S90: Program mode, ISO 80, Default Image Parameters,
    Manual white balance (preset), + 1.0EV
  • Canon PowerShot A520: Aperture Priority mode, ISO 50, Default Image Parameters,
    Manual white balance,
     
  • Lighting: Lighting: Daylight simulation, >98% CRI

Note: the Canon A520 shots were taken before we changed the lights in our fixed studio setup. This explains the different exposure values and pattern of reflections.

Although the Sony S90 image has slightly more aggressive reds (and slightly higher overall saturation), there's not a lot between these two models in terms of colour, tonality or noise (hardly surprising given they almost certainly share the same sensor). What is interesting is that - on the evidence of this test (and our resolution chart images) - the Canon lens has a slight edge on the Carl Zeiss optic sported by the S90. It's not a difference you'll really see in a small print, but there is no doubt the A520 is capturing more detail than the S90.
