Bit the bullet and picked this puppy up last week. Due to family commitments I was unable to properly take it out since I bought it. F5.6 under fluorescent lighting in a shopping mall - this is the second shot that I took with the lens!

What I'm sure we all really want to see is wide open performance. With this image I've done small tweaks to the white balance. It is tack sharp to the corners. Possibly this is the sharpest lens that I have shot yet on a 35mm camera at the focus point. Sharper than the Sonnar 55 1.8.
