From the conclusions: “Image quality is very impressive, with results that compare exceptionally well against a full frame sensor. You do pay a small price in terms of corner softness and CA. The biggest remaining challenge, however, with the Canon EF to Sony NEX mount is AF speed, a direct consequence of pairing a PDAF-optimized lens on a CDAF sensor.” Click here.

I’ve received also an email from Daniel, who linked me his article posted at Steve Huff’s website. “The Metabones Speed Booster adapter: A COLUMBUS EGG“. See his shot and read his impressions here.
