Dear All,
I have a Panasonic Lumix DMC-FZ38.
I would like to buy a telephoto lens to start taking wildlife shots.
Checking the Panasonic site there are some accessories available for this model. I think I will need an adapter ring, but I am confused about 2/3rd lenses, thread diameter etc.

Basically, I need advice about if this is possible and what I need to buy if so. Obviously, this is my first venture in to photography and do not want to spend an enormous amount. I thought about 200 on the lens.

Many thanks.
