ตัวแปลง SVBONY Camera Lens Adapter for Nikon F-mount lenses
Ful metal construction provides a long service life
Designed for Nikon F-mount lenses (not for Z type lenses)
Brass ring is used to fix eyepieces to prevent the eyepieces from falling off and saratching
Please note: Allthough the manufacturer photos uses an eyepiece to connect to the rear of the adapter, a more practical use case will be to use cameras with a 1.25" nosepiece with extension tubes in between for photography applications.
