This advanced technology ensures extraordinary optical performance, delivering improved corner sharpness, reduced distortion, and minimized vignetting.

The Speed Booster Ultra 0.71x is expertly crafted using exotic materials at the forefront of glassmaking technology. It is well corrected for use with virtually all full-frame SLR lenses, regardless of exit pupil distance, making it a versatile addition to your camera kit. It performs exceptionally well with professional-grade f/2.8 zoom lenses, transforming them into high-speed zooms with excellent contrast and resolution.

The adapter is compatible with a wide range of Canon RF cameras, EF-mount lenses, and EF-Extenders, as well as lenses from Carl Zeiss, Sigma, Tamron, and Tokina. It also works with Contax N mount lenses modified to Canon EF by Conurus.

It features precision-machined brass with chromium plating on both the camera-body and lens sides, ensuring smooth mounting, an attractive appearance, and long-lasting durability. The lens side of the adapter boasts a robust leaf-spring structure, strengthening the adapter-lens connection and reducing wear.

The adapter also includes industry-leading electronic interfacing technology from Canada, offering true electronic control of the lens' aperture directly from the camera body. This allows for automatic aperture selection in P or S exposure modes, or manual selection on the camera body in A or M modes. The adapter also supports EXIF data such as lens identification, focal length, and aperture.

In conclusion, the Canon EF Lens to RF-Mount T CINE Speed Booster Ultra 0.71x Adapter is a high-quality, versatile tool that enhances the functionality and performance of your camera, making it a valuable addition to any filmmaker's kit.
