50-140mm Continuous AF in Single AF mode

[dvz]

I've been having issues with my 50 -140mm missing focus.  I most often use in on a tripod in controlled lighting situations, so I turn off OIS.  Manual focus doesn't seem to be an issue, but on the rare instances when I just want to get and lock focus I set the camera in S-AF.  I notice that the focus is continuously fore and back focusing all the time and my focus is hit and miss.  S-AF is the same as C-AF.

 

Does anyone have this problem... or know how to solve it?

 

Thanks!

I believe I saw something about that in the manual but cant remember where.

Looks like if you are using the AF-L button on the rear of the camera, you can customize how this button works, regardless of camera body (front button) set to S-AF or C-AF.
