I use this on my new P7800 Which is the successor of the P7700. Because the original Nikon what not in stock I settled for this one, and I do not regret it. It's cheaper but is just as good, all metal and very easy to attach and disasttach. Only down part, as with all solar caps on a 28 mm or less angle, in use with the original camera flash you get a shadow. Not to blame on the item itself ofcourse, but be aware of it before you take the picture or use a flash setup Which is mounted higher up on the camera.
