Fotodiox Pro Macro Extension Tube for Canon RF Mount MILC Cameras

The Fotodiox Pro auto macro extension tube for Canon RF-mount mirrorless cameras is a versatile accessory that allows you to increase the distance between your camera and lens while still maintaining electronic functions. This increased distance provided by the extension tube helps to shorten the lens's focusing distance for macro photography and also enhances the focal length of your lens.

Equipped with gold-plated contacts, this extension tube enables autofocus, autoexposure, aperture control, and image stabilization. However, it is important to note that autofocus may be slower at closer distances. Additionally, since there are no optics inside the extension tube, the optical qualities of your lens are preserved.

This Fotodiox Pro extension tube is a cost-effective alternative to purchasing expensive macro lenses for Canon RF-mount mirrorless cameras such as EOS R and EOS RP. It should be noted that this extension tube is not compatible with the Canon RF 35mm f/1.8 ISD Macro STM Lens.

When using extension tubes, it is recommended to use lenses with shorter to medium focal lengths for optimal results, as they are less effective with telephoto lenses. It is important to keep in mind that extra magnification may amplify camera shake and subject details, so using a tripod is advised. To ensure better image quality, set your lens to the smallest aperture (largest number) to achieve adequate depth-of-field.

Each ring of the extension tube brings you closer to the subject as you increase the distance between your camera and lens. Different lens lengths may require adjusting the distance from the subject until it is in focus. The effectiveness of extension tubes diminishes as the focal length increases, and caution should be taken when using extreme wide-angle lenses to avoid hitting the front lens element before achieving proper focus.

The Fotodiox Pro extension tube maintains the electronic functions of your lens, including auto-focus and auto-exposure, and features an all-metal construction with a smooth surface for easy mounting. With no optical insert, the extension tube ensures that your lens's optical quality remains uncompromised. You can also combine multiple tubes to achieve various macro ratios.

For added peace of mind, this extension tube comes with a 24 months warranty. Please note that all images are for illustration purposes only, and the actual product may vary slightly due to ongoing design improvements.
