Nikon AF-S TC-20E III -- An Essential Teleconverter Lens

Nikon is a Japanese leading multinational corporation well known for optics and imaging products. They produce cameras, microscopes, binoculars, measurement instruments and steppers used in photolithography. Nikon introduced the world's first teleconverter called Nikon AF-S Teleconverter TC-20E III SLR (Single Lens Reflex) Lens.

The dimension of this lens is 66 x 46 mm (2.6 x 1.8 inches) (Diameter x Length). The lens gets constructed with a combination of seven elements in five groups. The teleconverters get attached in between the camera body and telephoto lens in order to multiply the focal length without affecting the closest focusing distance. It has a Nikon F-Bayonet type of lens mount. The maximum and minimum apertures of this lens get reduced by two stops. The closest focusing distance will be same as that of the prime lens. The maximum reproduction ratio will be twice as that of a prime lens.

The magnification factor comes at low light transmission and reduces the minimum aperture of the lens. This teleconverter is greatly designed and it gets perfectly fit with the Nikkor type telephoto lenses. It features rubber seals around the body mount. The optical conversion factor is 2x which doubles the focal length of the attached lens. It doubles the focal length of compatible Nikkor lenses and provides an affordable and portable gateway to the extended telephoto reach. It comprises an oversized button to quickly remove the gloved hands with ease.

This teleconverter contains an aspherical lens element that virtually eliminates flare and other type of aberrations even at wide apertures. It is neatly designed to fit the Nikkor range of lenses. It comes with a new optical design. This teleconverter is best compatible with VR, autofocus and metering couple systems. For protection the teleconverter comes with a storage pouch and newly designed caps. The teleconverter TC-20E III reduces the aperture in two stops. When the user attach f/2 aperture lens such as AF-S VR 200mm f/2G, the minimum aperture of the lens becomes f/4.

The tough mechanism offers extraordinary performance to the user. The supplied accessories with this teleconverter are Flexible Lens Pouch CL-0715, Teleconverter Cap BF-3A and Rear Lens Cap LF-1. It weighs 330 grams (11.6 ounces). The integrated coating raises the light transmission efficiency and improves the color consistency. It delivers brilliant image quality. It is very easy to handle. The aspherical lens element provides first class image quality and is best suitable for sports and wildlife photography.
