The answer to that depends upon how close you want to get. If you set your FZ150 to 12 mp, the focus switch on the lens barrel to "AF macro" (the flower symbol) and zoom it all the way out then "zoom with your feet" until you can get it to focus on the subject (generally about 3 ' distance) you'll get a good shot. Folks who add on a macro lens can get much closer (detailing the face of a bug) but with varying (and usually, shallower) depth of field. It also helps greatly to turn OFF all "iZoom", "ezoom", "digital zoom" features and let the glass do the work rather than messing up your shot with pixellation from the in-camera software.
I would try that and see if you are happy with the results before shelling out to try a different camera.
