The Canon Extender EF 2X series III converter allows, as its name suggests, to double the focal value of a Canon range lens in EF mount, without altering either the performance of the optics or the quality of the final render. For example, transform a 100mm into 200mm or a 70-200mm into 140-400mm! You have 2 focal ranges very easily available.
Among other things, it allows you to keep control of the aperture as well as the autofocus.
In addition, being directly connected to the camera, the Canon Extender EF 2X series III keeps all the automated connections of the camera and the lens. Adjustments can be made directly on the housing. Optical glass notably improves the sharpness of the corners as well as reducing vignetting and distortion.
Impervious to humidity and dust, it offers very good communication between the camera and the lens, which allows an autofocus and a quality exposure measurement; while weighing 325g.
Compatible with L series telephoto and telephoto lenses, also available at French Production Service.
Available in Kit; French Production Service, in partnership with Sunsetcam, can also provide you with complete sets including this focal doubler on equipped cameras, ready to shoot.
