The Hama Lens Rear Cap for Nikon is a must for any photographer using a SLR or DSLR camera. This little piece of plastic is engineered to simply be positioned onto the mount at the rear of a lens when it has been removed & twisted to lock it into place.
It itakes just a second or two to position this & saves a lot of time & effort in cleaning the rear element, a fiddly & precise task. This rear lens cap also helps to protect the lens mount itself & the essential electronic contacts around it from accidental damage because of the way that it fits snugly onto the lens mount.
