1) It doesn't sound severe enough to noticeably impact image quality. Try a test roll when it comes back, and if it looks fine, I wouldn't bother.
I have been shooting with it for a while. It's fine, great even. I think my concern is just weather since the issues with the lens have already begun, whether they'll continue to worsen over time. If that's the case, I want to rewind time and buy a cleaner copy that's earlier on it's life. But that's just dependent on whether the lens of my 2.8F is going to be ok from now on.
If you want to see side-by-side tests, take one shot with the lens wide open, and another with the lens stopped down to f/3.5.
Duh, why didn't I think of this?? haha
