The Nikon 180-400mm f/4E TC1.4 VR is a versatile super telephoto lens with a built-in 1.4x teleconverter that offers the option of shooting at an effective 252-560mm a first for Nikon. Because it is built directly into the lens, there is very little light falloff with this teleconverter and sharp imagery is maintained. This sophisticated optical design is paired with a Silent Wave Motor for quiet operation, weather sealing, and stabilization including special sport and tripod modes. It has blazing fast lock-on tracking, especially when used with a camera that supports Nikon's 153-point AF system (their most advanced AF system at the time of this writing). cameras with this system include (but are not limited to) the D6, D5, D850, and D500. This lens also provides a more consistent exposure during burst shooting thanks to a newly-designed electromagnetic diaphragm system that syncs with your camera's shutter (versus the mechanical linkage levers of blades in D/G lenses). Despite its enormous reach, this super telephoto is smaller, lighter and more comfortable than prior models, which gives you a better opportunity to deploy handheld shooting and also makes transport easier. This lens creates masterful images of wildlife and is a powerhouse for sports, graduations, safaris, and more.
