Bower 2x Autofocus Teleconverter Lens For Nikon F

Vintage-style Bower High Definition II 2x Digital Autofocus Teleconverter lens for Nikon SLR/DSLR cameras (Model: SX4NIK). Made in Japan. This high-quality optical accessory features 4 multi-coated elements to reduce lens flare and ghosting while doubling the focal length of your existing lens setup (e.g., turning a 300mm lens into a 600mm telephoto lens). It maintains full autofocus and electronic coupling with compatible Nikon F-mount camera bodies and brighter lenses.  Comes packed with both front and rear protective lens caps (including an authentic Nikon rear cap). Excellent lightweight gear addition for wildlife, sports, or action photography.  Condition: New old stock (NOS) contents inside an open, heavily worn box. The teleconverter barrel and optical glass are completely unused, pristine, clean, and scratch-free, safely protected inside the factory plastic wrap. The original retail box shows significant shelf wear, crushed edges, and a small tear along the top opening tab.
