Metabones Speed Booster Review by LensRentals

Canon 50L Sample on NEX-7 with Metabones Speed Booster
(effective 35mm f/0.9)

LensRentals posted their review of the Metabones Speed Booster. The Speed Booster lens adapter tested was a Canon EOS to Sony E-mount variant mounted on a Sony NEX-7. The lenses used were all Canon EF autofocus lenses, 14mm f/2.8 L II, 50mm f/1.2 L, and the 135mm f/2.0 L. The Speed Booster promises a one stop light improvement and a 0.7x focal length conversion. The lenses are effectively converted to 10mm f/2, 35mm f/0.9, and 95mm f/1.4 as seen by the Sony APS-C sensor.

So what was their conclusion after their test?

I think it was pretty obvious that I came armed for battle, ready to slam this product as some marketing overhype. I was wrong less correct than I might have been. The Speed Booster does what they claimed it would do, much to my shock and surprise. It creates a wider-angle, greater aperture lens while retaining resolution and acutance.
