Canon's EF 400mm f2.
8L IS III USM Lens demonstrates a true mastery of photographic optics.
Aside from the phenomenal optical features of this lens, one of the main aspects to highlight is the Mark III version's much light design, enabling handheld shooting.
The lens also has a wide and bright maximum aperture of f2.
8 which provides an extensive control over depth of field and confident use of the lens in low/difficult lighting conditions.
Canon has equipped Super UD and fluorite elements that are used to reduce colour fringing and chromatic aberrations for high clarity and colour accuracy.
There's also Super Spectra and Air Sphere Coatings that have been applied to suppress flare and ghosting which in turn increase contrast and colour neutrality when working in backlit conditions.
This potent mix of expert craftsmanship, a super telephoto range and a f2.
8 aperture make this lens perfect for wildlife and sport photography.
