The LC-CP26 Lens Cap from Nikon is a side-squeeze/snap-on type of lens cap designed to fit the Nikon COOLPIX P7700 Digital Camera. Lens caps protect the lens from scratches, fingerprints, dust and moisture when not shooting. It is a good idea to have a spare lens cap in case you lose the original when on vacation or assignment. Keep it in your camera bag so there is no risk of lens damage if (and when) you lose the original cap.
The front filter mount on the COOLPIX P7700 is 40.5mm, so this lens cap should fit on any lens with a 40.5mm front filter mount diameter.
