 Canon EF 500mm f/4L IS II USM US$10,399

Canon EF 500mm f/4L IS II USM is one super telephoto lens acclaimed by both wildlife and sports photographers. It is indeed "bulky and heavy" in nature, but still widely regarded as "relatively compact and lightweight" compared to its super telephoto lens peers. Photographers can occasionally try shooting with this lens without the use of a tripod. Its constant aperture of f/4 is capable of capturing moving objects in low light conditions with the satisfactory clarity and sharpness. The lens' 9-blade aperture also improves image impressions and creates a softer background.
