Product Details / Description:

Renting the EF 1.4X III is the most cost-effective way to add extreme reach to your existing high-quality telephoto lenses while traveling. It is an indispensable tool for capturing intimate shots of birds, monkeys, or other wildlife you might encounter in the Japanese countryside or national parks.

About the Product

The Canon Extender EF 1.4X III features a sophisticated optical design of 7 elements in 3 groups to ensure minimal optical degradation. Flare is significantly reduced by thoroughly treating reflections inside the lens barrel, ensuring high-contrast images even under strong light.

A key benefit of this L-series accessory is its environmental sealing. When combined with weather-resistant EOS camera bodies and compatible EF lenses, it forms a robust system that prevents the intrusion of raindrops and dust, enabling super-telephoto shooting even in harsh weather conditions.

Note that when attached, the effective maximum F-number is reduced by one stop (e.g., an F4 lens becomes F5.6). Depending on the attached lens and the camera body, autofocus may be disabled, requiring manual focus.

Key Features

• 1.4x magnification of master lens focal length.
• High image quality maintenance across the entire image field.
• L-series professional weather sealing.
• Compatible with a selection of Canon EF telephoto and telephoto zoom lenses.

Faqs:

Which Canon lenses are compatible with this Extender?

The Extender is primarily designed for use with high-quality Canon EF telephoto prime and telephoto zoom lenses, particularly the L-series (e.g., 70-200mm F2.8L, 300mm F4L, 400mm F2.8L). Please confirm your specific lens is compatible before renting, as not all lenses can be used.

How does the extender affect the aperture of my lens?

The 1.4X extender reduces the effective maximum aperture by one full stop. For example, if you attach it to an F2.8 lens, your new maximum aperture will be F4. If you attach it to an F4 lens, the new maximum aperture will be F5.6.

Will autofocus still work when I attach the Extender?

Autofocus functionality depends on the effective maximum aperture created when the Extender is attached. Most modern Canon bodies will maintain AF if the effective maximum aperture is F8 or brighter. If the effective aperture is dimmer than F8 (e.g., F11), autofocus may be disabled, requiring manual focus.

Does the Extender affect the minimum focusing distance?

No, the Extender does not change the minimum focusing distance of the master lens. However, since the focal length is extended, you achieve a higher maximum magnification, which is useful for close-up work from a distance.

What does the weather-resistant construction mean for use in Japan?

The weather resistance provides protection against light splashes of water and dust when the Extender is mounted between a sealed EF lens and a sealed EOS camera body. This is crucial for shooting outdoors during Japan’s rainy season or in dusty environments like dry riverbeds or trails.
