● 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 and 3 are also available. (*^_^*) ※ Please note that the [G mount] for Fujifilm you are currently viewing is completely different from the popular [X series]. The [X series] is listed separately. Please also refer to the third photo for reference. It's a bit complicated with all the different standards, isn't it? If you don't understand, please ask. ※ X series (XF) and G mount (GF). ********************************* ↓↓ 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 for the shipping cost, so please feel free to comment. ■ Some design changes may occur.
