Perhaps the most "sensible" of the items presented in this list, this is nevertheless one of the heftiest tele zoom lenses for SLR cameras around. While the zoom range of 200-500mm is nothing new or exciting, it's the maximum aperture of an incredible f/2.8 throughout the focal range that makes this such a special lens.

While a lot of tele lenses have a distinct cannon barrel look, Sigma have apparently done all they can to enhance that trait, giving the lens a leafy green finish. The end result is an extremely fast tele zoom lens that could easily be confused with a surface-to-air missile launcher.
