I have a freak of a lens, the 50mm 1.8G. I think there's something wrong with mine! It's TOO SHARP!!!
This particular shot is I think ISO 3200-6400. I have Luma at 50%, which softens the image considerably!!! Even though it's been reduced from its 12.1 mpx, the original is tack sharp, with hardly any noise (love that D3 sensor).
It beats the Sharpness of the 135L that I rent on occasion. A frikken $200 lens, can you believe that?!!! I can't do portraits with this lens, because it reveals the veins in eyes. I have to dial the clarity back to -31 for portraits. It's NUTS!
