Used Sony 2x Teleconverter Lens

The Sony 2x Teleconverter multiplies the focal length of the lens used by 2x without degrading optical performance, AF speed and precision, or operability. Light loss with the teleconverter is approximately 2 stops. An ideal way to extend available focal length range for sports or wildlife photography without having to carry additional large, heavy lenses.
