Allowing you to extend the focal length of your compatible lenses by 1.4x, the EF Extender 1.4x III could be a very handy addition to your photographer’s kit. Mounted between your Canon EOS DSLR and a compatible lens, a lens extender such as the EF Extender 1.4x III can provide many benefits. One of the main advantages of this extender is its ability to increase focal length, and in doing so, it allows you to frame your subject more tightly and adjust the angle of view in your shot. Investing in an extender can also help you save money, by increasing the focal length range of your current lenses, while also saving you valuable space within your kit. Offering similar build quality to Canon’s superb L-series lenses, this teleconverter is weather sealed and durable. It also offers improved build quality, delivering sharp images with well controlled flare, distortion and chromatic aberration.
