I recently picked up a Vivitar Series 1 19-35mm wide angle zoom, mostly for 
use on a trip later this month.  I'll be using it with an LX, but when I 
tried it with a Pz-1p it was apparent that you could not manually focus at 
the wide end without some sort of aid.  Using the AF sensor on the Pz-1p 
gave surprising results - the lens could be several feet (even several 
meters) off focus per the distance scales on it, but the AF sensor would 
show it as in focus.

To test things further I put my only wide angle AF lens, the F 17-28 
fisheye, on a Pz-1p and tested the AF.  Standing inthe doorway of a room 15 
feet long, and focusing on the far wall, the AF locked focus anywhere from 
4 feet to infinity, based on the distance scales on the lens.  (Most of the 
time focus was set at about 4 feet.)  These results were duplicated with 
two other AF bodies - another Pz-1p and a Pz-70.

On the flip side, the split image finder on the LX is remarkable accurate.

Given the great DOF of these lenses, I don't know if it really matters 
(I've used the F17-28 on AF several times without any problem.)  I'd be 
interested if newer generations of SAFOX or other camera brands are more 
accurate.
