■Canon EF Lens to Sony NEX Adapter
■Increases Maximum Aperture 1 Stop
■Increases Angle of View by 0.71x
The Canon EF Lens to Sony NEX Camera Speed Booster from Metabones allows Canon EF lenses to be mounted to Sony E-Mount APS-C format cameras, increasing the angle of view and the maximum aperture of the lens by 1 f-stop. This photo accessory also comes with a detachable tripod foot that is compatible with Arca Swiss, Markins, and Photo Clam ball heads.
The Speed Booster condenses light from the lens and projects it onto the APS-C sensor without vignetting; this allows the sensor to capture all of the lens' transmitted light and effectively produce full-frame coverage on non-full-frame sensors. A corresponding increase in the maximum aperture of 1 stop makes the lens more effective in low-light situations and able to create a shallow depth of field.
Metabones' Speed Boosters are made of machined brass, finished in satin black, the camera-body, and chromium-plated on both mounts to ensure smooth mounting and reliability.
These speed boosters are only fully compatible with mirrorless cameras housing APS-C or smaller image sensors. They will physically fit the Sony A7/A7R full frame mirrorless cameras but the camera must be set in Crop Mode to fully support the speed booster's functions.

1.Vignetting at corners may occur for certain EF-S lenses because they are designed to cover a 1.6x crop image circle but Sony NEX has a 1.5x crop sensor.
2.Image Stabilization lens?requires adapter firmware version 02 or above.
3.Requires lenses supporting distance information.
4.A third party zoom lens may need to be registered with the Smart Adapter first in order to detect its maximum aperture. Autofocus is disabled for most third-party lenses.
5.For example, some improperly-made M42 screw mount adapters may cause a short-circuit with the electronic contacts of the Smart Adapter??and cause damage to the Smart Adapter??and/or camera body.?

The T Smart Adapter Mark IV for Canon EF or Canon EF-S Mount Lens to Sony E-Mount Camera from Metabones allows a Canon EF or EF-S mount lens to be mounted onto a Sony E-mount camera. While doing so, the adapter is designed to support electronic communication between an attached camera and lens. If the lens includes autofocus, image stabilization, as well as camera-controlled aperture functions, this adapter is intended to allow those features to be used. If an attached lens is also capable of generating EXIF metadata when used with a directly compatible camera, the T Smart Adapter Mark IV for Canon EF or Canon EF-S Mount Lens to Sony E-Mount Camera is designed to allow that information to be saved along with image files generated with a combination of the lens, a Sony E-mount camera, and the adapter.
By enabling camera-controlled aperture functions for a Canon EF or Canon EF-S Mount Lens when used with a Sony E-mount camera, program, shutter-priority, aperture-priority, as well as manual modes can be set and used through the camera. Power for these functions is transferred from the camera to the lens, and the T Smart Adapter Mark IV for Canon EF or Canon EF-S Mount Lens to Sony E-Mount Camera is designed to accomplish this in an energy-efficient manner. When manual focusing is preferred with a compatible electronic lens, an integrated switch can be depressed which opens the lens's aperture diaphragm to it largest setting. The resulting shallow depth-of-field can then be used to help ensure focus accuracy.
When an image is taken with the T Smart Adapter Mark IV for Canon EF or Canon EF-S Mount Lens to Sony E-Mount Camera, a matte black internal coating minimizes the potential for reflections within the adapter barrel, which could otherwise result in unwanted glare within the image. The adapter barrel also features a wide internal diameter to support the movements of compatible tilt-shift lenses.
The T Smart Adapter Mark IV for Canon EF or Canon EF-S Mount Lens to Sony E-Mount Camera is constructed from aluminum alloy for durability while minimizing weight. Its mounting rings are made with brass to further prevent wear-and-tear, and a detachable tripod foot is included that features 3/8" threads as well as compatibility with Arca-Swiss tripod heads.
While Canon EF-S or third-party APS-C EF-mount lenses may be used with the T Smart Adapter Mark IV for Canon EF or Canon EF-S Mount Lens to Sony E-Mount Camera, vignetting may occur when such lenses are combined with this adapter and a Sony E-mount camera with an APS-C sized sensor. Canon EF-S and third-party APS-C EF lenses are designed to project an image onto sensors measuring 22.3 x 14.9mm, while Sony E-Mount APS-C cameras feature sensors that measure 23.5 x 15.6mm.
The T Smart Adapter Mark IV for Canon EF or Canon EF-S Mount Lens to Sony E-Mount Camera can be used to connect Canon EF or third-party "full-frame" EF-mount lenses to a Sony E-mount camera with a "full-frame" sensor without vignetting. It may be used to adapt Canon EF-S or third-party APS-C EF-mount lenses to a "full-frame" Sony E-mount camera as well. However, Sony E-mount cameras with a "full-frame" sensor must be set to "crop mode" when combined with this adapter and Canon EF-S or third-party APS-C EF-mount lenses to avoid generating images with vignetting.

Adapts E-Mount Camera to PL Mount Lens
Note: If you want to use your existing PL mount lenses on a camera with a Sony E-mount, you need an adapter. The Metabones PL to E-Mount Adapter mounts to your camera's lens port and allows you to use PL mount lenses with your camera. Although this is not a permanent conversion, the adapter features a removable support foot to take the strain off of your camera's mount.
