I bought mine on ebay. It was stated as mint but at the arrival there were several fungus threads between elements. Unfortunately after disassembling the lens I found that front and back elements are factory sealed and fungus can't be removed. Even plastic part of the front element was damaged. Anyway I killed the threads using concentrated sunlight, I washed each parts in medical alcohol and it stopped spreading. I'm not a professional photographer but it isn't influencing the image quality and I can shoot insanely sharp and good pictures.
Overall it's a really good value. I hesitated between F1.4 and F1.7. Maybe I'll invest in a F1.4 later but right now I'm satisfied with its sharpness, low light shots and bokeh.
You don't need to close aperture for sharpness because it's sharp at 1.7. But at 2.8 it goes insanely sharp even at the edges.
Fungus at front element:
It was a surprise at cleaning. Force damage on plastic of the front element:
After this shock I'm still satisfied with the results:
