Viltrox EF-E II Auto Focus Lens Adapter 071X for Canon EF to Sony E-mount Camera
Viltrox EF-E II Auto Focus Lens Adapter 071X for Canon EF to Sony E-mount Camera
Viltrox EF-E II Lens Adapter Auto Focus with 0.71 Booster for full-frame Canon EF-mount Lens to Sony E-mount Camera 0.71xFocal Lenth Multiplier Equivalent to expanding the aperture by one stop!
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.
If a lens intended for 35mm film or similarly-sized full-frame camera sensors is connected to a Sony E-mount camera, it would project an image larger than the camera's APS-C sized sensor was built to accept. Able to capture only the center portion of the projected image, the effective angle of view of the lens would be narrowed, creating an in-camera "crop factor." This adapter condenses the light from a lens designed for 35mm film or "full frame" camera sensors and projects it onto a Sony E-mount camera's APS-C sensor. This allows the APS-C sensor to utilize more of the light gathered by a connected lens, which effectively reduces the crop factor while making available to the sensor an additional one stop of light for each of the lens's f/stop settings.
If a compatible lens includes autofocus, as well as camera-controlled aperture functions, this adapter is intended to allow those features to be used. Also, if an attached lens is capable of generating Exif metadata when used with a directly compatible camera, this adapter is designed to allow that information to be saved along with image files generated with a combination of the lens, a compatible Sony E-mount camera, and the adapter.
This adapter is constructed with four lens elements in four groups that are designed to provide optical clarity as well as color 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.
Upgraded Function (Comparison with EF-E I):
Two Auto Focus Model :
a) PDAF(phase detection auto focus): Focus speed is faster.
b) CDAF (contrast detection auto focus): Focus success rate is higher.
Firmware upgrade can be operated via the USB port.

Warm Tips from our photographer:
0.71xFocal Lenth Multiplier Equivalent to expanding the aperture by one stop!
If your lens is 50mm Focal lense, then: 50mm x 1.6=80mm
if your lens is 50mm Focal lense with our 0.71x Adapter Mount, then 50mm x 1.6 x 0.71=56.8mm, Equivalent to expanding the aperture by one stop!
If your lens is 35mm Focal lense, then: 35mm x 1.6 =56mm
if your lens is 35mm Focal lense with our 0.71x Adapter Mount, then 35mm x 1.6 x 0.71=39.76mm, Equivalent to expanding the aperture by one stop!
The PRO Auto Focus Lens Adapter Mount with 0.71x Focal Lenth Multiplier, You deserve it!
Warm Tips:
To update adapter firmware, latest firmware can be download from official website, connect adapter to computer with USB cable and copy the file into adapter memory. Do not required to attach lens or camera.
To change AF mode, switch to desired AF mode on adapter, then turn off camera, take out battery, insert battery and turn camera back on again for camera to recognize new AF mode as a new lens. Slow focus will happen on low end lenses in CDAF mode.
