This should be the first K-5IIs sample that posted online, via a forum post at Photo Malaysia here.
In the same thread, we can see a pair of comparison pictures on the K-5II and K-5IIs sensors and their different appearances:-


Via this post here, in the same discussion thread.
Well, I like the appearance of the K-5II sensor better, it looks clearer and more transparent after all.
Btw, if you wish to see the official comparison illustrations by the PR about the difference between the K-5 and K-5IIs, read the opening post of the above thread here. The diagrams were displayed at Photokina as exhibits.

Thanks for cross referencing my test shot in your blog. I shall be doing some studio portraiture test with the K5IIs next Tuesday, and will share them at DPReview right after. Will try to compare it against the AA filtered K5II.
My initial assessment has been very positive so far.
Stay tuned.
Cheers,
Wesley
