An adapter that adds a piece of glass usually does not result in a high
quality macro lens. Some, clip on lenses for the iPhone can produce a
reasonably decent quality image. If you do your research, you will see
which ones work for you. Similarly, some close up attachments for a P&S
camera may, give you a satisfactory image, but that is not very likely.

unless the camera's lens can be removed and replaced with an actual
macro lens, something which is highly unlikely on a p&s, a closeup lens
is the only viable option.

as with everything, there's a range in quality, with the better closeup
lenses producing very good, if not excellent results.

among the better options is the canon 500d, a *two* element closeup
lens (versus the usual cheaper one element). not surprisingly, it's not
cheap, and like other closeup lenses, it attaches on the front of the
lens so it will work with nikon, sony and other lenses, not just canon.

Most inexpensive P&S cameras don't have high quality sensors or glass.
Again, do your research, as you will find that some P&S cameras will
give you what you want.

that part is true, but someone buying a p&s is more concerned with
convenience than quality. in other words, it's 'good enough'.
