Gooderham Flatiron Building -- NEX-5 & Taylor-Hobson 75mm f2.
Found out the this lens has a de-centering problem. 1/3 of the frame is blurry. Not sure if it's the lens, or all the adapters/rings put on it. I have a feeling when gluing on the adapter ring on the back, it was not perfectly flat. Will see if I can remove it and re-glue it. Other than this, I am very happy with the lens.
