Unlike the lens cap provided with the camera there is no need to remove this one, the cap opens and closes automatically as you turn the camera on and off. At first how to fit it on the front of the lens was a bit of a mystery. I assumed that there was a ring on the front of the lens which would unscrew to allow the threaded lens cap to be installed, but the camera is so well made that this did not appear to be the case and I was afraid to use too much force. However the suppliers of the lens cap assured me that the outer flange of the lens would, in fact, unscrew and so it proved. Panasonic should consider this as original equipment. I wouldn't be without it.
