To test if it is a focus issue, you could try manual focus mode and see if you still have the problem.


Forgive me for stating something obvious, but um, the camera buffer wasn't full, was it? I mean, is the camera slow right when you turn it on, or only after shooting a bunch of shots in succession?


One more thing- are all the pictures in the same folder? If so, try no more than 100 per folder and see if that helps. (I'm really grasping at straws with this last one...)


Best of luck.
