The FT-1 Mount Adapter allows you to use certain legacy F-Mount NIKKOR lenses (those designed for use with Nikon D-SLR/SLR cameras) on the Nikon 1 V1 and J1. The Mount Adapter is attached to the Nikon 1 V1/J1 and the F-Mount NIKKOR lens then attached to the adapter.
This L-Plate allows fast and easy swapping from landscape to portrait without the need for an L-plate on your camera.
Note that this L-plate is not compatible with the Nikon 1 V1 L-plate set, rev A. You must remove the B1V1-L Set (rev A) when using the Mount Adapter with L-plate.
