Key Features
- Adapts Lenses with B4 Mount
- Mounts on Sony E Mount
- Maintains Infinity Focus on Lens
- Brass & Stainless Steel Construction
The Fotodiox Pro Lens Mount Adapter B4 to Sony E Mount allows you to use available lenses that feature a B4 mount to fit on a camera body with a Sony E mount. The B4 mount is traditionally used on lenses designed to work with 2/3" 3-imager sensors. This is a lens mount adapter designed to attach to the lens itself, it is not meant to permanently adapt the mount of the camera. The adapter mounts to the lens and is removable, so you can use one adapter on many different lenses.

The adapter is 1/2?
It is not. This is an adapter that will allow you to use B4 Lenses that are for 2/3 cameras. They do not make such adapters for 1/3 and 1/2 B4 Lenses.

question
Has anyone used it with an FS7 with the current firmware which includes the 2K centercrop? And what have been your findings?
My findings are that it doesn't fit a b4 lens and is therefore completely useless for its intended purpose. I'd avoid
