All, one of our favorite simple cameras, the Canon SD850, is no longer sold; so we have been trying out its "newer neighbor," the SD880. The results are somewhat encouraging, although it does have some vignetting against the blue sky at full zoom. Some examples worth looking at (thanks to Kilgore and Marti for these):
Coal Mine
By the River
Queen Square
The detail at full zoom is reasonably good, which is good news.
