I vote for 13. mosen, since the photo makes me actually feel a bit acrophobic. Honorable mention to Maemish for getting that nice picture out of the good old N900!

And to juiceme's question above: the piggz advanced camera is at least most of the time better at focusing on the Xperia than stock, but never worse. The only reason I can think of not to use it is it's less "Sailfishy" in the interface. E.g. there's a button instead of a swipe to view previously taken photo.
