Any PnS that can do macro as close as 3 cm?

[Sausage]

Are there any recommendations for this purpose?

theres a few that can even go down to 0cm, focusing on the dust on the lens.. the S5 IS is one such cam..

But keep in mind that when it does go as close as 0cm, a shadow usually shows up in the photos. Of cse, it depends on which direction the light comes from. I own a S5IS, so I find that I face this problem.
On hindsight, if I had the money, I'd probably go for a DSLR with macro lens. But I am digressing as you are talking about PnS.
