The Nikkor Z Teleconverter 2.0x is suitable for telephotography with the Nikkor Z 70-200mm f/2.8 lens. This converter increases the focal length with 2x, so you can zoom in on your subject even further. That's useful at places where you can't come close to your subject, like wild animals and birds. You keep on using the technologies of the camera, like image stabilization and fast autofocus. Thanks to the dust proof and splash proof casing, you can also use the converter in moist, dusty, or cold circumstances.
