MF have relatively less DOF so you'd have to consider if you want that. I don't see why they would be less sharp though. One other thing you need to know is the light loss, because the bigger frame...

Well, the first impressions are pretty good hey? No rolling shutter effect so far either. What is exactly the problem with the filter? Does the front of the lens rotate when you focus?

I'd try a gray filter. Stopping down the lens (on either one) will only increase the vignetting. A central grad filter like Dan suggested would be even better.
