I ordered a Lensmate adapter for my digital camera last monday, and it just showed up in the mail today. This adapter will allow me to use the filters pictured above on the Powershot G2. The three filters in the foreground are the set of Hoya macro lenses. They can be stacked together for varying powers of magnification.

Of course, Murphy's Law being what it is, the adapter
showed up late in the afternoon and I have to go back to
work tomorrow, so I won't really get to play with the new
toys until Friday. :-)
