This compact, 400mm version II lens from Canon's professional lineup is ideal for handheld sports and wildlife photography. Lens is in absolutely pristine condition... not a single mark on it. Protected with a Lens Coat covering from Day 1. Purchased new in 2019, and includes the original front lens cover, lens hood, original foot, and hard case. All like new. Also included is a Wimberley replacement foot with Arcas Swiss mount (retails for $100 US). This lens is still in Canon's current lineup and provides superb contrast, sharpness and nice bokeh for the professional wildlife photographer. Image stabilization provides up to 4 stops of compensation. I have used it with both the Canon 5D Mark IV body as well as the R5 body (adapter required), with and without 1.4X and 2X extenders. Image quality is excellent even with the 2X extender. Sample hi res images are available upon request. Retails for $9300 new plus taxes. Price is firm. This is essentially a new lens at less than half the price. $4500
