Canon EF 600mm 1:4 L Series IS USM Ultrasonic Lens.  Lens and accessories all work great.  Neoprene covers have been on the lens for quite some time, eveident in minimal scratches and dings on lens paint.  Comes with what is shown in photos.  Includes Drop-in Screw Filter Hodler 52mm.  Includes optional "Seymour Solar" filter for photos of the sun and eclipse photos. Also includes neoprene covers for protection and adds camoflage for nature photos. Carrying case shown in photos is included and in good shape.
