Here are some sample shots from the NEX-7 and the Contax Zeiss 28mm f/2.8 Distagon using the Metabones Speedbooster. It was great shooting the 28mm at close to its natural focal length. The lens was always set wide open at f/2.8 and the NEX-7 was at ISO 100. We are very pleased with the Speed Booster.

TheCameraStoreTV posted their hands on video with the Metabone Speed Booster for NEX cameras. They used the Canon EOS to NEX Speed Booster lens adapter on the NEX-7.
In the video they compare the NEX-7 and the Nikon D600, a full frame camera, to see if there are perceptible differences. They used a Sigma 35mm f/1.4 DG HSM lens on both cameras. The exposures were set to be equal at ISO 200 and aperture set at f/8. The NEX-7 with the Speed Booster registered and aperture of f/5.6 due to the full stop of light from the adapter. The D600 registered f/8. The image above is a side by side comparison at 400% enlargement. Would you be able to tell the difference?

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.
