A quick look at the new Metabones EF - E Mount Speed Booster on a Sony FS700.
This adapter essentially increases your lens' aperture by a full stop, and widens the lens by 0.71, making it closer to its Full Frame equivalent on the Super35 FS700.

Lenses Used:
Canon 70-200mm f4.0 L
Rokinon 35mm Cine t1.5
Sigma 30mm f1.4 EF-S (or whatever Sigma's equivalent name is for that)
Tokina 11-16mm f2.8 EF-S (ditto above)

Please note that this is not designed to work with EF-S lenses, but they can still be used with slight to major vignetting in some cases.
