Metabones "Speed Booster": results & influence on choice of camera bodies and lenses!
Metabones + Dr Brian Caldwell announced their new "Speed Booster",
actually a well known principle from astronomy, a focal reducer or telecompressor.
See here:
Metabones - Metabones and Caldwell Photographic introduce Speed Booster
White Paper is here:

Test is here:
An adaptor which claims to make your lens, faster, wider and better!! This is NOT an April Fool’s! | Philip Bloom

Done that before for my sort of photography, see on my BLOG:
Photography of the Invisible World: Search results for reducer
without reducer/telecompressor:
with reducer/telecompressor:
overall system changed from f4 to f1.6 and the focal length from 84mm to 34mm!
