Adam from Mythbusters talks about Speed Booster and NEX cameras.
An anonymous SAR reader just sent me that youtube video you see on top of this post. It shows Adam Savage of the incredibly popular Discovery TV show Mythbusters using EF lenses with the Metabones Speed Booster on three of his NEX cameras (inncludes the NEX7 and the SONY FS700).
