Are there any recommendations for this purpose?
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.
