I recently took my camera on a trip (not for the first time, but it was effectively the first time I was really able to use it)... and found myself very disappointed with the results using the W-20 lens.
In full telephoto (and hopefully you'll forgive any incorrect terminology or whatnot, I'm far from a professional photographer), there is vignetting in the picture. It's small enough to be difficult to see in the preview screen, but definitely noticeable in the photo when viewed on a larger device. It can be edited out, of course, but it's still mildly annoying.
On the other end, as everyone knows, you can't zoom in to full wide angle because the required short port blocks the lens. Mildly annoying, but "just don't do it" seems to be the answer to that problem...
The big issue is that the quality of lens itself is not that great. When I took shots with the camera zoomed in, the extremities of the picture were extremely blurred, and looked absolutely terrible. I had to throw away several shots and crop the heck out of others. I've attached the worst example.
I guess the best I can hope for at this point would be to install the CHDK firmware on my G9 and maybe set it up to limit the zoom range so neither effect (blurring or vignetting) are visible.
