With my Nikon D700 yes, but with the D4 no, it locks on very fast and no 
dithering in low light.  No problem at all with the R8DMR. ;)

Cheers,

Subject: [Leica] IMG: Autofocus Nightmare

While seeking an inhouse diversion on a very cold day, I set up a gray 
aircraft model in front of a black background, wanting to get a very low key 
image.  I tried two different AF lenses on my E-510 and neither could lock 
on and hold focus on the subject.  Perhaps it was the low light environment, 
but they kept changing focus, seeking something they liked.  I grabbed a few 
shots that were roughly in focus, as well as a lot that were out of focus.  

Here is the image:

Have others experienced this sort of behavior?

Comments and critiques welcomed.
