Double your Nikon lens' telephoto power

Sometimes you need more reach than your lens can deliver, but buying and toting a longer lens may not be an option. That's where Nikon's TC-20E III teleconverter comes in. Attached between your Nikon camera's body and a compatible Nikon lens, it effectively doubles the lens's focal length without adding significant bulk. For example, using the converter with Nikon's AF-S 70-200mm f/2.8 ED VR II lens increases its zoom range to 140-400mm on a full frame (FX) SLR such as Nikon's D610 (or a whopping  210-600mm on a DX cam like the D7100). And the TC-20E III's high-quality optics maintain your lens's sharpness, while its built-in Silent Wave Motor allows most lenses to continue autofocusing normally. It's perfect for shooting outdoor sports and wildlife scenes where the added telephoto capability can really come in handy.

Features

Overview: The AF-S Teleconverter TC-20E III is a precision optical accessory, mounted between the camera body and the lens. It has a 2.0x optical conversion factor, which effectively doubles the focal length of select compatible Nikkor lenses. It is ideal for sports photography, wildlife photography, surveillance, and more. The TC-20E III has the standard Nikon F-bayonet mount, and is compatible with FX, DX, FX in DX crop mode, and 35mm film formats. A list of compatible lenses can be found below.

Nikon Integrated Coating (IC): The TC-20E III has Nikon's integrated coating which enhances light transmission efficiency, improves color consistency, and reduces flare.

Autofocus: The TC-20E III allows auto focusing with most compatible AF-S lenses, many with manual or auto priority. With some compatible lenses, though, auto focusing is not possible. Focus assist may also be available in most situations.

Lens Construction: The teleconverter has 7 lens elements in 5 groups, including 1 aspherical lens element to eliminate coma and other aberrations, especially at wide apertures. It is optimized for use with FX and DX digital SLRs.

Exposure: The use of this teleconverter decreases the effective aperture of the attached lens by two stops. With most AI-type cameras, exposure is determined in the same manner as using the prime lens only. Exposure cannot be determined with the G-type lens. For non-AI-type cameras, you will need to perform the stop-down method to determine the proper exposure.
