With the K-5 IIs moire is eliminated as soon as you pass into the diffraction limit which is around f9. From what I can tell around f8 and smaller the benefits of removing the AA filter become negligible. Yes I do realize you eek more resolution out of a filter less sensor even at smaller apertures, but you quickly reach diminishing returns. That's why I passed on the K-5 IIs. The AF wasn't enough of an upgrade and I shoot outside, stopped down to f8 or smaller typically. With the 24MP of the K-3 it will likely outresolve a lot legacy lenses and probably a lot of lesser modern pentax glass too. The limiteds could keep for the most part up I'm sure. This isn't such a bad thing. IMO you pretty much always want the sensor to outresolve the lens anyways. You benefit from the full effect of the lens painting the image, which can be interesting with using legacy lenses. I'm not too worried about full frame challenging pentax legacy glass either. Quite a few of those lenses are definitely good enough for people to be using on canon full frames and honestly IMO once you get beyond 24MP on even full frame you might as well start looking at medium format if you really need more. The D800 outresolves all but insanely priced lenses. If I was going to spend money like that, I'd get a 645D used and start building up a small set of primes. PS: I wouldn't worry about moire too much. It should be a lot better than the k-5 IIs was, which wasn't bad.
