I got a D7100 several months ago as a second camera to my D300, but I had not been able to use it until recently. I am finding that the autofocus is not working properly. Comparing to identical settings with my D300, putting it on a tripod to assure the same distance, etc. - it ain't workin'! Particularly with my 80-400mm at length, the results are very soft. I have seen a number of people mentioning the same issue in various areas of the Net, but not with UHH. Anybody having similar problems?

I believe it has less to do with "professional" anybody, than with the general lack of courtesy in the culture, that is growing. But I am an "old guy", so I think in those terms, any more...
