Looking to pick up Panasonics 43mm Wide Angle Lens...anyone know if it's full zoom through? If not, anyone have any good recommendations for a full zoom through model for my GS400?

Raynox HD6600 is confirmed to be full zoom through with the GS400 and is a high grade wideconverter.

If you want a better one but heavier one, check out Raynox HD7000.

One thought is that these Raynox lenses may be full zoom through in the movie mode, but may vignette slightly when stills are taken to card. Worth checking out if you intend to use them this way.
