A quick post of a 10 sec clip from Judder of a focus pull done manually on a Pentax K100D DSLR with a 18-55 lens. I painted a little dot lining up the beginning of the focus pull and other to mark the end, with an arrow to show which way to go (first time didn't do that and it came back to bite me in the @!) I just used the little ridges on the lens as guides, a third of a line per frame, animating every 2nd and 3rd frames to ease in and out.
