● This is a "rear cap" to protect the back of the camera lens and prevent dust from entering. It is a compatible product. Having spare caps on hand gives you peace of mind when changing lenses. ● Sets of 2, 3, and 5 are also available. (*^_^*) 【Note】The product you are currently viewing is for Nikon "N1 (Nikon1)", not Nikon "Nikon-F". The explanation is difficult, but for most general Nikon cameras, it is Nikon "Nikon-F". It's quite complicated, isn't it? Please ask if you don't understand. "N1 (Nikon1)" is basically for small-sized mirrorless cameras. We also have various "Nikon-F" products available. ********************************* ↓↓ Common product description from here ↓↓ ■ If you can't find it, or if you are purchasing multiple items, we will create a "dedicated page" with a discount on shipping costs, so please feel free to comment. ■ Some design changes may occur.
