Sony 1.4x Teleconverter - E mount
The Sony 1.4x Teleconverter with Sony E-mount multiplies the focal length of the lens used by 1.4x without degrading optical performance, AF speed and precision, or operability. Compact and lightweight, the lens offers an ideal way to extend available focal length range for sports or wildlife photography, without having to carry additional large, heavy lenses. Light loss with the teleconverter is approximately 1 stop.
