◆ Nikon camera cap & lens mount caps. ◆ These caps are for protecting the lens mount when separating the lens from the D7000 body. They are attached to the mount on both the body and the lens. ◆ These came with the camera when it was returned from overseas repair, and as you can see in the photo, they are simple. I believe they are not for sale, but I don't know the details. ◆ Large: Inner diameter approximately 5.5cm, Small: Inner diameter approximately 4.4cm
