This will eventually get sorted out. Too bad you had to bail.
Worst case scenario would be a hardware problem that Pentax never admits to and resolves via replacement models.
Originally posted by pentaxkr Recieved another KR kept it a week, tried to do what everyone talked about, still not great results, finally brought it back to B & H who again did fine job. Went to Nikon counter and got a Nikon, could not be happier with the results. I was a Pentax user for over 20 years but am very disappointed could not continue.
