I don't know the 300/4.5, but I have had some issues with the FA*400/5.6 at long exposure times. Especially when rotated to portrait position. It performs better with the MZ-S than with Z-1, presumably because the MZ-S shutter is better damped.
Bj�rn's work on Nikon lenses is very interesting, and most likely have transfer value to most brands.
