I do not know if my reply is in good time...

I have this lens and I'm more than satisfied with it.

If you take picture in the same camera position with GFC1 the sharpness decrease is insignificant, You can see it only with pixel-hunting.

This is a good study on this topic:

Just don't go shooting brick wall tests with it, and you'll be happy. I haven't used mine since I got my PL 8-18, but made extensive use of it previous to that. The car shots in the linked post are taken by me.
