I liked the Pentax FA 400mm f/5.6 ED IF right away; it’s not particularly heavy, and can be used with the camera mounted on the tripod head, no need to mount the lens; this is more stable. I heartily recommend it to any 645D user.
At long focal lengths, blur from the shutter itself can be a problem, even with mirror lockup. In this case, I used ISO 400, and I also mounted the camera to the tripod (not the lens), which is a more stable setup (but not suitable for heavier lenses). Even so, 1/60 is a problem.
This is the entire frame as shot (shade).
