16mm performance ?

Have a look at Photographyblog's samples from the NX1000 , there`s a RAW of an urban scene with a graffiti covered iron bridge and it`s shot at 50mm wideopen , it`s absolutely tack sharp . the JPG version is there too if you don`t use RAW - my 20-50 is nothing like as good at 50mm ..
