FZ200 - moving objects
Tried to edit above post but was too late. If you want to get sharp moving subjects with any camera you must use a high shutter speed. If you were shooting in a store with f2.8 you probably did not have enough light to get a high shutter speed. Also if you were shooting at 300mm your shutter speed should be at a minimum 1/300 of a second but even better would be at 1/450th of a second. Are you sure you had fast enough shutter speed for the zoom you were using.
