Actually the Canons have this same method of focus and zoom. The
Attachment is a metal ring that extends beyond the reach of the lense, and the
filters are screwed on beyond the reach of the lense (about 1.75 inches, with
the filter, on a Canon PowerShot). Seems a bit low tech, but it
works. If you leave it on all the time, it makes the camera a tight fit in
a little camera bag for digitals though. I don't know if this is so for
the Sonys, but many things are similar between Sony and Canon. On the
Canon and some of the others, there is a little button adjacent to the lense
(usually lower left) which releases a little metal ring that has little purpose
beyond decoration (perhaps keeps some dust out). The metal ring will twist
off just like the lenses of most SLR cameras, and then you can twist on the
adapter (or other lenses that are designed for the particular camera).
Pearl's suggestion doesn't seem to work well on my cameras, because they
readjust to what they are looking at as you move them, and it's hard to keep the
focus and the exposure settings and still keep the flower in focus when you
change locations. Even so, I'm going to try harder to follow it, because
the polarizer doesn't always fool the camera.

Dave -- Thanks for the tip. As
it happens, my camera, a Sony DSC-W7, has an automatic zoom that retracts into
the body of the camera -- so, no place to attach a filter. Pearl's
advice ( a couple of posts after yours) seems to be working, though.
