Anyone know about the K-r's AA filter?

<p>According to tests by Photozone, the K-5's AA filter causes a degrading of border performance with certain lenses, like the FA 43mm Limited. Apparently, the FA 31mm Limited is unaffected, as are the DA Limiteds. I seem to recall, however, seeing excellent landscape shots posted by Justin Serpico, using the 43mm Limited on his K-5 which did not seem to have this shortcoming.</p>

<p>I have not been using this lens on my K-5, but relegating its use with continuing fine results on my K200D and K20D. But what about the K-r? I assume its AA filter is akin to that of the K-x, and unlike that of the K-5? Is it more like those incorporated in the K200D and K20D?<br>
