K&F CONCEPT NIK (G)-NEX Nikon F Lens (G) to Sony E-mount adapter, in excellent condition. This adapter has an aperture ring, allowing you to mount Nikon F-mount G-type lenses (lenses without an aperture ring) on Sony E-mount bodies. It also works with older lenses that have an aperture ring. This is one of three adapters I am selling. I only used it for test shots, so it's like new, with no scratches or marks. I'm reluctantly selling it due to an unexpected change in my camera system. Thank you.
