Unfortunately there are also some people who take it personally when they don't even own a K-5 to begin with...
To all K-5 and other new camera newbies, my suggestion is don't go starting threads at the slightest notice purporting supposed problems and getting overly paranoid about things before you actually read the bloody manual from start to finish and take the necessary time to familiarize yourself with the camera. If there is really a genuine problem, get it exchanged or send the camera in for service.
It would help to use the search button and read past threads and plentiful posts that may have been discussed earlier at length, instead of starting threads on a whim asking for help or advice just because you don't know wtf is happening. That way, you'll avoid most of the negativity and impatience that might come when newbies pose basic and often stupid questions. As newbies, don't always expect instant answers by posting threads claiming about issues that for the most part might be wholly unfounded or that you probably are not fully aware off. Instead, search judiciously and read up first instead of always expecting to be spoonfed or having your angst reassured. I think it is human nature for others to find this sort of behavior pretty tiring, hence the wall of negativity.
