Thanks, don't worry to find any more! I tried with the 50mm again today and it was so much better. The 16-55 is perfect when things aren't moving, but maybe I should get it checked.

One thing I have noticed with the 50-140 is if I am zooming while using AFC and shooting - I tend to have a higher number of bad focus than I would expect.  If I am not zooming - namely using the lens as a fixed focal length it works better.  When I was using the Nikon D800E and the Nikon 70-200 f4 for the track - I had virtually now misses and I simply held down the AF-On button and shot while I zoomed.  The H1 and 50-140 well not so much.  if I zoom, then hit AF and then shoot, drop out of AFC Zoom, and then hit AF and shoot I get much better results than keeping AFC engaged, and zooming while shooting.

That might be what you are experiencing.  My 50 to 140 is rock solid if I am not doing AFC, zooming to track action and firing shots at the same time.  If I am using it that way I can expect out of focus images.
