This is an adapter kit. A lens is not included!

The MTF B4 Lens to Sony E-Mount Camera Adapter Kit includes two lens adapters, a B4 2/3″ to Canon EF adapter and a Canon EF to Sony E adapter. The kit enables the use of ENG style B4 2/3″ lenses on cameras with either Sony E-mount or Canon EF mount, like the Sony NEX-FS100 / FS700U / FS700R 4K and Canon EOS C100 / C300 / C500. Key features include:

High Quality Optics and Build. The Multi layer coated optics ensures there’s no loss in image quality, while the solid aluminum construction is strong enough to support the rigors of heavy lenses.
Included Support Bridge. We include a support bridge that helps support the weight of heavy lenses when using a 15mm rod support system.
Please Note:
– In order to avoid vignetting, the B4 2/3″ lens will need to have the 2x extender engaged and the camera’s image sensor should be Super 35mm or smaller. For highest image quality, HD lenses are recommended.

– This adapter does not provide power to the lens. B4 lenses will require their own power source.
