Viltrox Canon EF to Sony E Mount Booster MK II

Mint condition, as new, minimal use.

This 0.71x Lens Mount Adapter from Viltrox allows a full-frame Canon EF-mount lens to be mounted onto a Sony E-mount camera. While doing so, the adapter's optics help to maximize the connected lens's apparent angle of view while providing a one-stop increase for the camera over the lens's aperture range.

This adapter is constructed with four lens elements in four groups that are designed to provide optical clarity as well as colour fidelity, and the underside of its detachable tripod foot is tapped with a 1/4"-20 accessory thread, enabling direct attachment to tripods or quick release plates that feature 1/4"-20 mounts. For ease of upgrading its firmware, this adapter also includes a micro-USB port.

For compatible Sony E-mount cameras that feature phase-detection and contrast-detection autofocus, a toggle switch to enable those autofocus settings with a connected Canon EF-mount lens is positioned along the side of this adapter. To properly apply a desired autofocus setting, the toggle switch selection must be made prior to placing the adapter on the camera.

This adapter is compatible with the Sony NEX-5C, C3, 5N, F3, 5R, 6, 7, FS700, VG20, and VG900 cameras.
