I don't have any experience with the Panasonic teleconverter. I've been using a Raynox DCR1540PRO 1.5xconverter and I am very happy with it. The Raynox lenses are less expensive but still good qualtiy lenses. Most people around here areusing the Olympus TCON-17 another good converter for less money than the Panasonic.

Thanks Vaiboy. I assume you still need the Panasonic lens adapater? Do you know of any websites that sell the Raynox DCR1540PRO at a good price? Thanks again :-)

PS Do Raynox also do a compatible wide lens converter?

I bought my Raynox lenses through Amazon.com, so I don't remember the exact store. Raynox makes a large selection of lenses, I have the DCR6600 wide angle converter also. I really like thier macro lenses too. http://www.raynox.com/

Thanks for all your advice. Its been very helpful. :-)

I use an Olympus C-180 teleconverter I bought from Olympus eBay store for 9.99 US plus three dollars shipping and tax. It darkens at the edges in poor light, but if I need it I am usually cropping anyway. It does not need a converter, screws right into the tube that came with the camera. Most recent bird posts I have put up the shots were taken with the tele converter.
