NEX-7 with Sigma 30mm: insanely sharp!

Still very impressed how sharp the Sigma 30mm f/2.8 is on the NEX-7. No doubt it is a fine lens, but it is almost like if the two were meant to be used together.

Below are 2 pictures taken with this combo at f4 and f2.8, with their respective 1:1 crops. Both are handheld. Click on Original for bigger size images.
