Sean Rivers shares this excellent review on the PhotographyandCinema.com PR-1 Shoulder Rig [Thanks Sean]. The P&C PR-1 shoulder rig is bundled with a basic set of rails, clamps, Swiss Rods, extended handles, and shoulder pad for beginner shooters, but can easily be expanded with other Industry Standard 15mm accessories. The baseplate of the PR-1 was originally designed for smaller cameras, but with a Manfrotto quick release baseplate added, Sean was able to mount up his Sony FS700.

A short while ago, I discovered a new Canon EF/EF-S Lens Adapter to Sony NEX Camera systems. It's basic function is similar to the more expensive Metabones adapter in which you can control the electronic iris of the lens natively through the Sony NEX camera body. I have confirmed that it works great on my Sony NEX-7, and here Landon has his own review and confirmation of it working great on the Sony FS700. [Thanks Landon]. As mentioned in the video review below, it's half the price and also easier to obtain than the metabones product also.
