Hi, I have a 400mm Pentax K-mount Vivitar F6.3 telephoto lens that would work for you. It comes with one Polarizing Filter, one Skylight Filter and two UV filters. All are in excellent condition with no scratches, hazing or fungus. The lens has a built-in retractable hood and a tri-pod attachment point that balances the camera better on the tripod. I will sell the lens and the filters for $75 if you will pay the shipping costs. I guarantee everything to be in excellent condition. If you are not satisfied, I will return your purchase price if you pay to ship it back. It takes nice photos at a great distance. I use it on a Pentax K-50 DSLR for nature and animal/bird photos. This is a good lens without paying several hundreds of dollars for a newer one. If you are interested, you can reach me at
