The second image with the Nikon lens. I don't know what you think of this but I am very impressed by the image quality. There's a bit of a glow at f1.8 but stopped down one or two notches and it is very sharp. This will be my one and only Nikon lens that I will own. I had to try one out to see what all the fuss is about these lenses. I'm not going to sell it either because it is one of the sharpest manual focus lenses that I have tested, and one can never have enough 50 f1.8 lenses about the house...right?
