Thanks for the link. I trust GordonBGood.
But it's strange that Pentax applies a stronger AA filter than Nikon and Sony. I am curious how the various companies handle the 'bare' sensors sold by Sony. Does each one look for a different company to provide the AA filter and ADC electronics etc?

Certainly. The K10D (Sony 10mp) had a very special AA sensor - no filtering on the vertical axis, strong filtering horizontally. The NEX-5 has a similar approach, BTW.
The K5 has a symmetrical AA filter (as most).
The hardware post-processing is also very different - see e.g. the A700 vs D300 in terms of high ISO noise despite a very similar sensor.
