It indeed looks like a EF 100-400mm f4.5-5.6 L IS USM II which focal length range has been extended to 500mm, without the aperture also being extended (to contain costs and weight?).
The 100-400mm has a max aperture of f5.6.
f5.6 / 400 x 500 = f7... Makes sense in the Canon universe. If only the $1400 Nikkor 200-500mm f5.6 did not exist...
