Product Details / Description:

The Canon EXTENDER RF 1.4x is a valuable rental option for tourists using Canon R series cameras who frequently find their telephoto lenses just a bit too short. It easily attaches between the camera body and a compatible telephoto lens, instantly multiplying the reach by 1.4. For instance, an RF 400mm lens becomes a 560mm lens, expanding your shooting possibilities across Japan.

About the Product

This teleconverter utilizes advanced optical engineering to effectively increase your lens’s focal length while preserving the high imaging performance you expect from Canon RF optics. The modest reduction of only one stop in maximum aperture makes this extender a great choice for shooting in varied light conditions where maximizing reach is critical but maintaining aperture speed is still important.

Its robust construction and precise fit ensure reliable performance and seamless communication between the lens and the camera body. This makes the Extender RF 1.4x an indispensable tool for traveling photographers who want professional reach without the bulk of dedicated super-telephoto glass.

Faqs:

How much light does the EXTENDER RF 1.4x lose compared to shooting without it?

When using the EXTENDER RF 1.4x, the effective maximum aperture (F-number) of the attached lens is reduced by one full stop. For example, if your lens has a maximum aperture of F5.6, using the 1.4x extender changes the maximum effective aperture to F8. This minimal light loss helps maintain good low-light performance.

Can I use this extender with my Canon RF 70-200mm F2.8 L IS USM lens?

No, the EXTENDER RF 1.4x cannot be used with all RF lenses. Due to the design of the protruding optical element, it is only compatible with specific RF telephoto lenses, such as the RF 600mm F11 IS STM, RF 100-400mm F5.6-8 IS USM, and RF 100-500mm F4.5-7.1 L IS USM, and others in that telephoto class.

If I use this extender on the RF 100-500mm lens, what is my new effective focal length?

The maximum focal length would be extended by 1.4 times. The 500mm end of the zoom would become 700mm. The new effective aperture at the long end would also change from F7.1 to F10.

Does the autofocus speed significantly slow down when I attach the 1.4x extender?

Autofocus speed and precision are generally well-maintained, particularly on high-end Canon R series bodies. Since the aperture reduction is only one stop, the camera’s AF system has ample light to work with in most conditions, offering a minimal reduction in performance compared to the 2x extender.

What are the physical restrictions when using the 1.4x extender with the RF 100-500mm lens?

Similar to the 2x extender, due to the construction of the RF 100-500mm L lens, the EXTENDER RF 1.4x can only be mounted and used when the 100-500mm lens is zoomed to a focal length of 300mm or longer. This prevents the rear element of the zoom lens from colliding with the extender’s optics.
