Vello Accelerator Lens Adapter for Canon EF-Mount Lenses to Sony E-Mount Cameras

Pair your existing Canon EF-mount full-frame lenses with a modern Sony E-mount mirrorless camera and experience the coveted "full-frame look" on APS-C format sensors with the Accelerator Lens Adapter from Vello. By using a specialized 4-element, 4-group optical design, this adapter is able to increase a lens's angle of view by a factor of 0.71x while simultaneously increasing the maximum aperture by one whole stop. This allows a 50mm f/1.4 lens on an APS-C camera to maintain an angle of view close to 50mm while providing it with an f/1.0 equivalent aperture. This setup means full-frame lenses can be adapted to APS-C sensors, or full-frame cameras in APS-C crop mode, without losing the desired natural look of a full-frame system.
