New patent discloses a new Sony 50mm f/1.2 and f/1.4 fast lens!

The Japanese blog Egami found a new Sony patent that describes the characteristics for two new standard lenses. A new 50mm f/1.2 and a new 50mm f/1.4 fullframe lens. Those are the specs:
- Patent Publication No. 2011-107450

I guess that those would be welcomed updated of the current 50mm f/1.4 from Sony. Check the specs and price of that lens by clicking those direct links: [shopcountry 7134]. A new and well praised alternative is the Sigma 50mm f/1.4 which you can get at [shopcountry 6765].
