Pair your existing Nikon F-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 in 4 group optical design, this adapter is able to increase a lens' 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. Along with this, the adapter features a manual aperture ring with an 8-stop range in 1/2-stop increments.
Along with these capabilities the durable metal adapter features a removable tripod foot with 1/4"-20 socket for use on a tripod or support system, alleviating strain on the lens mount. Additionally, the purely mechanical adapter has a matte black interior to prevent reflections from interfering with image quality.
No aperture control will be possible when pairing this adapter with lenses featuring the newer electromagnetic aperture mechanism (e.g. Nikon E, etc.).
