Canon EXTENDER RF 1.4X

Extender RF 1.4x
Extend your range with a 1.4x multiplier specially designed for the RF lens system, delivering excellent image quality and unmatched communication speed between camera and lens.

Expand your vision
The Extender RF 1.4x is the perfect choice for avid and professional photographers looking to enhance the magnification capabilities of their RF lenses. With a focal length multiplied by 1.4, it is perfect for press, sports and naturalist photographers.

More depth without loss of image quality
The multiplier incorporates a high refractive, low dispersion glass to control field curvature and chromatic aberration of magnification for optimum image quality.

Advanced lens design
In addition to the optimized lens treatment, the 3-layer optics help reduce ghosting by minimizing the air contact surfaces.

Designed to operate in extreme conditions
The exterior has the same white insulating coating that is used on the RF 100-500mm F4.5-7.1L IS USM and RF 70-200mm lenses to prevent degradation of performance at high temperatures.

Seamless integration with the RF 100-500mm F4.5-7.1L IS USM
A zoom mechanism limiting the focal range of the RF 100-500mm F4.5-7.1L IS USM (300-500mm) prevents elements of the lens from coming into contact with those of the multiplier.

Uncompromising construction
Designed for optimum reliability and durability, with resistance to shock, vibration, dust and water, it is suitable for both professionals and discerning hobbyists.
