Compared to...

Below you will find a studio comparison between the Canon PowerShot S70 and its nearest competitor, the 7MP Sony DSC-P150. We have included samples for the lowest and highest ISO settings for each camera (Canon S70: ISO50 and 400, Sony P150: ISO100 and 400).

Studio scene comparison (Canon S70 @ ISO 50, Sony P150 @ ISO 100)

  • Canon PowerShot S70 : Manual exposure mode, ISO 50, Default Image Parameters, Manual white balance
     
  • Sony Cyber-shot DSC-P150: Manual exposure mode, ISO 100, Default Image Parameters, Manual white balance
     
  • Lighting: Two 800W studio lamps with dichroic daylight filters bounced off the ceiling

Although both cameras have at their heart the same Sony CCD, there are some differences in the output image - some are lens-related, others are obviously the result of slightly different approaches to image processing from Sony and Canon. The overall tonal range is very similar, though the Canon S70's pictures are slightly warmer, with much more vivid reds and slightly less saturated blues. Detail from both cameras is excellent, but the superior Canon optics are obvious - especially at the edge of the frame (look at the writing on the batteries). Both cameras control noise very well at their lowest ISO setting, though the S70's advantage here is that it's lowest setting is ISO 50, which produces marginally less noisy images than the Sony P150's ISO 100. That said, it is worth noting that the exposure information would seem to indicate that the Canon's ISO 50 setting is roughly the same sensitivity as the Sony's ISO 100.
