Performance and Image Quality
For those of you familiar with the Canon SD800, the SD870's image quality is about the same, and that's a good thing. This Canon produces very high quality, detailed images which probably put it near the top when compared to its competition. Colors are accurate, and the images are very detailed. What's nice about this camera is that the auto-controls work so efficiently, unlike other cameras where the auto-controls fail to produce good, accurate results. It's a good thing that the auto-controls do work well in this camera, because there aren't many manual controls. That is an aspect that may turn some people away from this camera.
Image quality is great up to around ISO 400 where you can start to see a bit of noise in photos, although smaller prints should still be fine at this level. At ISO 1600, the image noise is very apparent, so I would recommend staying at ISO 800 or below whenever possible. When compared to the competition, the SD870 does a better job at controlling image noise at elevated ISO levels.
Performance is equally impressive in the SD870 with numbers very similar to those of the SD800. Recent independent tests have shown the average shot-to-shot times at about 1.6 seconds with a shutter lag of only 0.4 seconds. I found this camera to be one of the fastest cameras in its class, although it falls a tad bit short of the Sony DSC-T100. Nevertheless, I think most people will be satisfied with the exceptional image quality and speed of this camera, not to mention the great features and small body. This is a great point-and-shoot camera.
