I just found a deal on the K-5IIs a few weeks ago! I was so excited, especially after I found that it is
much sharper when paired with 18-135 WR than my original K-5 w/ the same lens. I think the K-5 was back-focusing with it, because I was not
used to getting "sharp" results. Anyway, seems like it's a little
too sharp with even my kit lens, because just in the first full week that I've had it, I found out to my chagrin that all the people who boasted that they've taken 10,000 shots and not seen a hint of moire, obviously weren't using this particular body...
First, here's a shot that I took the day after I got it, this is what really got me excited about the new "sharper" sensor.

That's better than I had dared hope for! I didn't realize that my 18-135 kit lens was even capable of such detail!
Now, I was asked to take some pictures of a family, and I happily obliged (a good chance to use my "new" camera!) So, I tried several different poses, and when I later started reviewing the photos, I found that there was a batch with one certain pose where
every picture had extremely noticeable and disturbing patterns. Here's what I was seeing (in varying degrees of awfulness) in
all 18 pictures...

Now, I wonder if this camera is specifically affected, or if anyone else has seen such a dramatic illustration of moire? I searched quite extensively through this forum, and a few people had started threads with their barely visible samples of false color, etc, but I don't think I saw anything quite this bad! (All of said threads quickly degenerated to arguments about whether or not the K-5 IIs is indeed sharper than the K-5 classic...
)
I did think to check my camera's firmware, and it turns out it is still running firmware version 1.00 I will update to the latest (1.07) and see if it helps, but I don't know if that would help any.
So, is there anyone else who has gotten such dramatic examples? I didn't take a limited lens and stop it down, and
hunt for moire, I was just taking snapshots outdoors in low-ish light, and here are 18 pictures in a row that all are practically ruined!
