Description:
The Viltrox EF-R3 PRO Lens Mount Adapter is a precision-engineered accessory designed to expand the compatibility of full-frame Canon EF-mount lenses with RF Mount Cameras. With a reduction factor of 0.71x, this adapter enhances the apparent angle of view of connected lenses while providing a one-stop increase in light transmission across the lens's aperture range.
When coupling a lens intended for 35mm film or similarly-sized full-frame camera sensors with an RF Mount Camera, the projected image would typically exceed the Super 35 sensor's dimensions, resulting in a narrowed effective angle of view and an inherent "crop factor." The Viltrox EF-R3 PRO addresses this by condensing the light from the lens onto the Super 35 sensor, optimizing light utilization and mitigating the crop factor, while also delivering an additional one-stop boost in light sensitivity.
This adapter facilitates electronic communication between the camera and lens, enabling the seamless operation of autofocus and on-camera aperture control if supported by the lens. Furthermore, it allows for the generation of Exif metadata when used with a directly compatible camera, ensuring comprehensive information storage with captured images.
Constructed with four lens elements in four groups, the EF-R3 PRO ensures optical clarity and colour fidelity, preserving the integrity of your images. Its detachable tripod foot features a 1/4"-20 accessory thread, facilitating direct attachment to tripods or quick release plates for added stability during shooting. Additionally, the adapter includes a micro-USB port for convenient firmware upgrades, ensuring compatibility with future camera and lens innovations.
