Thank you for looking. This is a pdmovie wireless focus system. I purchased it directly from the official store, but I've only used it for testing, so it's almost new (the box is damaged). Everything in the photos, including accessories, is included. I will also include the batteries I purchased additionally. https://www.youtube.com/watch?v=prnUhdOeHWA I am selling it at a low price due to decluttering my equipment.
