I would like a review and good description of the Tele Conversion Lens offered by Panasonic (the DMW-LTZ10). Is it made by Leica? Does it have threads on to add a UV lens? What makes it worth $500? Is there a tele converter lens out there that is a 2x?. Is is possible to have 2 tele converter lenses on the camera at once? How bad would the vignetting be? I like to take shots of birds and need a lot of zoom.
Here's my first photo using the Panasonic DMC-FZ20.
