Nikon AF-S Teleconverter TC-20E III

Product Summary


Retailing at $500 the AF-S Teleconverter TC-20E III simply doubles the focal length of a select list of compatible Nikkor lenses. It is a perfect tool to carry for medium range and even super telephoto lenses, increasing their effective focal length range to cover more distances. This is the go to teleconverter if you’re into wild life photography, action or sports photography or just interested in some candid shots.

A new feature of the AF-S Teleconverter TC-20E III (compared to the older TC-20E II and the original TC-20E) is the presence of Aspherical lens elements which takes away the spherical aberrations and ensures that the color saturation is perfect creating sharper pictures. Additionally the presence of Nikon’s Integrated Coating (IC) elements ensure that flares is suppressed resulting in improved contrasts.

The AF-S Teleconverter TC-20E III has a total of 7 lens elements arranged in 5 groups and is compatible with a select list of FX and DX F mount Nikkor lenses. It enables both AF (Auto-focusing) capabilities and has Nikon’s Silent Wave Motor (SWM) technology which ensures that focusing is quieter. However the teleconverter will auto-focus only with the AF-S and AF-I lenses. Conventional lenses will not have the auto focusing capabilities.

The dimensions of the lens is 2.6×1.8” (diameter x length). The AF-S Teleconverter TC-20E III ships with a BF-3A front lens cap, the LF-1 rear lens cap and the Cl-0715 lens case for easy transportation. The overall weight of the AF-S Teleconverter TC-20E III is only 330 grams. Available at Amazon | Adorama | B&H
