It's a Leica manufacturered 18X optical zoom with a 35mm equivalent of 28-504mm. The FZ18 is a super zoom class advanced Point and shoot, I'm afraid you won't be able to find this lens for your camera.
The only critters I get to shoot on my "estate" are those annoying little squirrels. Oh yeh.. I have a ground hog that's been digging holes in my yard too..
