Equally impressive were our ISO tests. Viewed full-screen and zoomed out they were difficult to tell apart, suggesting you should get decent prints at virtually any setting. Zoomed in, there was very little difference between ISOs 80 and 400.
At ISO 800 a little softness started to creep in, which became even less controlled at ISO 1600, Still, noise was never a really serious problem, and if you find yourself faced with low light at long focal lengths it's reassuring to know the SX210 IS's DIGIC 4 processor can take the strain.
This is particularly useful since the lens's maximum aperture when zoomed in is a comparatively-slow f/5.9.
