The New AF-S NIKKOR 400mm f/2.8E FL ED VR and AF-S Teleconverter TC-14E III

The New Nikkor AF-S NIKKOR 400mm f/2.8E FL ED VR: Superior Optics, Superb Handling
The new 400mm f/2.8 super-telephoto lens delivers upon the NIKKOR promise of uncompromising performance, thanks to overall enhancements to the optical characteristics of the lens, which go beyond simply enhancing image quality. With a refined optical formula, those who shoot fast action sports from a distance or rapidly moving wildlife will appreciate the improved autofocus (AF), exposure accuracy and speed.
Nikkor AF-S Teleconverter TC-14E III
Nikon’s long legacy and expertise in optical engineering is substantiated with this new 1.4x teleconverter that retains the lens’ image quality, even at wide-open apertures. This new teleconverter effectively multiplies the focal length of many NIKKOR lenses by 1.4x, while resulting in only a one-stop loss of exposure. Especially useful for nature and sports photographers, the enhanced optical system reduces chromatic lens aberration, while preserving the accuracy of the AF system.
