The MTF B4 Lens to Sony E-Mount Camera Adapter Kit lets you use ENG-style B4 2/3-inch lenses on Canon EF-mount and Sony E-mount cameras. Key features include:
Multilayer coated optics
Durable solid aluminum construction
Lens-support bridge included
Supports heavy lenses
What’s Included. The MTF B4 Lens to Sony E-Mount Camera Adapter Kit includes a B4 2/3-inch to Canon EF adapter and a Canon EF to Sony E adapter. These let you use ENG-style B4 2/3-inch lenses on Sony E-mount cameras like the FS5M2 and FS7M2, and Canon EF-mount cameras like the C300 II. This rental also include a lens-support bridge that helps support the weight of heavy lenses when you’re using a 15mm rod support system.
High-Quality Optics and Build. The adapters’ multilayer coated optics ensure there’s no loss in image quality, while their solid aluminum construction is strong enough to support heavy lenses.
This rental doesn’t include a lens.
These adapters don’t provide power to the lens. If you’re using a B4 lens, it’ll require its own power source.
To avoid vignetting, the B4 2/3-inch lens must have its 2x extender engaged, and the camera’s image sensor should be set to Super 35mm or smaller. For highest image quality, we recommend using HD lenses.
