Nikon 1.4X AF-S TC-14E III

(From company literature) Nikon’s long legacy and expertise in optical engineering is substantiated with the new 1.4x AF-S Teleconverter TC-14E III 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.

The construction of the teleconverter has been significantly upgraded for both durability and optical brilliance. Comprised of seven elements within four groups, the outer elements feature a fluorine coating for enhanced resistance to dirt and water droplets. For added durability, the lens barrel has been designed for increased moisture and dust resistance.
