Looks like randomized subject movement to me. I seem to get similar
images when I forget to input the proper focal length for the anti shake
system with a manual focus lens. Usually when I go from >200mm to 24mm.

So, after i set the Sigma 300 f4 APO's focus point a few weekends ago,
i set out Saturday to shoot a few back yard birds and such.
I did not have to review the photos in LR to tell which ones would be
in relative good focus and which ones could not focus. Its a hit a
miss but i'm now getting the odd shot like this:

Pretty much in focus, and then at times i get this:

Nothing will be in focus no matter how hard i try or use AF or MF.
Not sure what going on, the lens worked very well with the istD and k-10d.
Any thoughts??
