Default 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: http://www.metabones.com/images/meta...te%20Paper.pdf

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!
