Ideal for wildlife, birding, and getting close-up shots of distant landmarks or Mount Fuji from afar, the Extender RF 2x ensures high image quality is maintained, leveraging the advanced performance of Canon’s RF mirrorless lenses while maximizing your telephoto capability during your travels.

Quick Highlights:

  • Doubles the effective focal length of compatible Canon RF lenses (2x magnification).
  • Maintains the high optical quality of the attached master lens.
  • Ideal for capturing distant wildlife, birds, and far-off scenic landmarks.
  • Compact and lightweight design, much easier to carry than a separate long telephoto lens.
  • Essential accessory for maximizing the reach of telephoto zooms and prime lenses.
  • Simple and quick attachment between the camera body and the primary lens.

Product Details / Description:

The Canon EXTENDER RF 2x is a powerful tool for extending your photographic reach across Japan. Instead of carrying multiple large telephoto lenses, this compact extender allows you to instantly double your current telephoto lens’s focal length, offering an incredible new level of photographic flexibility, especially in nature parks or while observing distant spectacles.

About the Product

This teleconverter works by multiplying the focal length of the attached lens by a factor of 2. For instance, if you attach the Extender RF 2x to an RF 800mm F11 IS STM lens, the combination becomes an ultra-powerful 1600mm lens. While it reduces the effective maximum aperture by two stops, the resulting increased reach is invaluable for serious long-range photography.

The Canon Extender RF 2x features specialized optics that are designed to uphold the superior image quality of L-series lenses. Its inclusion of Canon’s high-performance elements ensures that images remain sharp, high-contrast, and free from excessive aberration, even at extreme magnifications.

Key Features

  • 2x Focal Length Multiplication: Instantly doubles the reach of compatible telephoto lenses.
  • Retains Image Quality: Designed to maintain the optical performance of the master lens.
  • Lightweight and Portable: Compact size makes it easy to carry in your travel bag.
  • Dedicated RF Mount: Ensures secure and reliable communication between the camera and lens.
  • Compatible with Multiple Lenses: Works seamlessly with popular telephoto RF lenses (e.g., RF 100-400mm, RF 100-500mm, etc.).

Faqs:

How does using the Extender RF 2x affect the lens’s maximum aperture?

When you attach the 2x extender, the effective maximum aperture (F-number) of your lens is reduced by two full stops. For example, if you attach it to an RF 100-400mm F5.6-8 lens, the new effective aperture range becomes F11-16. This is important for calculating exposure and understanding how much light reaches the sensor.

Which Canon RF lenses are compatible with the EXTENDER RF 2x?

The Extender RF 2x is only compatible with specific Canon RF telephoto lenses designed for it, such as the RF 600mm F11 IS STM, RF 800mm F11 IS STM, RF 100-400mm F5.6-8 IS USM, RF 100-500mm F4.5-7.1 L IS USM, and RF 200-800mm F6.3-9 IS USM. It cannot be used with standard zoom or wide-angle RF lenses.

Does using the 2x extender reduce the effectiveness of the Image Stabilization (IS)?

No, the Image Stabilization system built into the master lens continues to function effectively, even when the extender is attached. This is crucial because when you double the focal length, any camera shake is also magnified, making the IS system’s stabilization power essential for sharp handheld shots.

Can I use the Extender RF 2x throughout the entire zoom range of my RF 100-500mm L lens?

Due to the physical design of the RF 100-500mm F4.5-7.1 L IS USM lens, the extender’s front element cannot fit inside the lens when zoomed out fully. Therefore, the extender can only be attached to and used with the RF 100-500mm lens when the lens is zoomed to 300mm or beyond.

Is the autofocus (AF) still fast and accurate when the 2x extender is used?

Yes, the autofocus functionality, including the speed and precision of the Nano USM motor, is maintained. However, because the effective aperture is reduced by two stops, the camera’s AF system might perform slightly slower or less reliably in extremely low light conditions compared to shooting without the extender.
