Thank you for viewing! "Nikon Single-Focus Lens AF-S NIKKOR 20mm f/1.8G ED" Full-frame compatible ultra-wide single-focus lens As a bonus, a filter compatible with this lens is also included. "Kenko Camera Filter PRO1D Pro Softon [A] (W) 77mm" This filter was purchased for the purpose of taking pictures of the starry sky. Both items were stored in a dehumidified storage box. There is no mold or clouding, and the operation has been confirmed. I am selling it because I have had fewer opportunities to use it.
