Product details

Yongnuo Teleconverter Extender YN-EF 1.4 Version 3

The Yongnuo EF 1.4x III Teleconverter is designed for select Canon EF-mount lenses and allows you to increase the effective focal length of lenses for greater reach. The electronic design of the teleconverter enables communication between compatible lenses and camera bodies to support autofocus and auto-exposure. The optical design consists of seven elements in three groups to maintain image quality. The lens must be able to accommodate a teleconverter.
