Raynox AF-2000 Telephoto 2x (Unused)

A long time ago, I mistakenly purchased this at Yodobashi Camera even though I didn't own a video camera, and it has been stored at home for a long time.
The outer box is quite damaged, but the main unit itself is unused.
I do not know if it can be used with modern video cameras or how to attach it.
When deciding to purchase, please refer to the outer box display in the 9th image and confirm for yourself.

Additionally, price negotiations can become complicated depending on the response, so I cannot respond to any requests for price reductions.
