I have been thinking of posting a related question. When you determine
the per lens focus adjustment for a lens on one camera, does that number
tend to work on another camera, perhaps with a slight offset.
For example if on camera 1 you have
lens A +5
lens B +2
lens C -1
would you use the same numbers? Or if lens A works out to be +4, could
you assume that the corrections would be
lens A +4
lens B +1
lens C -2
Or do they end up just being totally random?

I am trying to sort out soft focus on my K-5 (especially with my 16-45/4 lens),
and would appreciate some help.
I put my camera on a tripod, used the picket fence in our back yard as a target
(with a card with an X sticking out), and shot repeated frames with 3 lenses
(40/2.8 Ltd, DA 16-45, and DA 50-200) using live view (LV) or viewfinder (VF)
autofocus. The focal length of the 16-45 was set at 34mm, and the 50-200 at
50mm.
The results:
40/2.8: FF in LV, very slight FF with VF
16-45: FF in LV, BF with VF
50-200: on target with LV and VF
Two questions:
1. I thought that the fine AF adjustment (via menu C4) did not affect Live View
AF. Is that incorrect?
2. What the heck is going on with the 16-45?
