Canon Extender EF 1.4x III

Ideal for press, sports and nature photography, this compact extender increases the focal length of Canon L-series telephoto or telephoto zoom lenses by a factor of 1.4x, with higher AF accuracy and improved communication between camera and lens.

The Extender EF 1.4x III is specially designed to work in conjunction with L-series IS super-telephoto lenses.  The extender's design ensures there is no loss of lens performance or image quality.

High-quality construction
Improved anti-reflection materials inside the lens-barrel and a coating around the outer edges of the lens elements reduce flare. Construction is resistant to dust and water, helping to maintain images quality.
Improved communication between lens and camera
A built in microprocessor provides accurate transfer of data from between the lens and camera delivering an improved performance in AF and metering.
Compatible with L-Series telephoto and telephoto zoom lenses
The Extender EF 1.4x III is compatible with most telephoto and telephoto zoom lenses within Canon's flagship professional L-series range, extending the focal length while only reducing the relative aperture of the lens by one stop.

"Excellent service and delivery from Castle Cameras,as usual."
Star Rating 5
By MartinGiess on 19th November 2018
"This extender is great giving me nearly 600mm from my 400mm canon lens, actually 560mm, when used on my full frame camera, or 896mm when used on the Crop sensor, and a lot cheaper than buying the equivalent size lenses. Would recommend"
