Selling my 500mm f4 P Nikon. I'm also including a modified Nikon 1.6A TC which has been modified to gives manual focus lens (AI, AIS, and P) autofocus with certain cameras. You can research more about this online. The image quality with the TC is superb and I've included a few sample images. This is a great way to get to 800 on a budget. This also meters correctly. I've owned this combo for about 5 years and I'm looking to go for something lighter. The lens is in great condition. The glass is flawless. No scratches or fungus. The aperture and focus are both very smooth. This comes with carrying case w/ straps and keys, hood, soft lens cover and drop in filter holder. There a few discoloration areas on the hood which you see on the photos. Please email me with any questions. US buyers only please.
