Using these particular samples as reference, I found that applying a deblur adjustement on the K-5 IIs resulted in an overcooked image. The same can be said for sharpening as the IIs which proved to have far less latitude than the K-5 II.

Topaz Detail contains numerous spacial detail enhancement tools which Raw Therapee lacks. Though the deconvoluted sharpening tool is based on the same technology. When I began this case study, I was using Raw Therapee exclusively. However, a forum member asked for a none RAW alternative and so I switched to Topaz Detail as as result.
Quote: When you try to reconstruct an image blurred by an AA filter, will you reconstruct it accurately? You could if you had an accurate enough 2D fourier transform, but the processing required would be horrendous. You're welcome to your opinion of course, but it seems to me that blurring an image and then trying to reduce the blur after the fact will result in a less accurate reproduction than simply not blurring it in the first place. Yes, I know, what about the dreaded moire? As I mentioned previously, I'm not worried about it, and so far I haven't seen it. If photos are rarely ruined by it, I'd rather have the vast majority of my images sharper and more accurate with less post processing. If others are worried about moire, then buy the K-5ii. Simple.
The topic of a script of tool to counter the effects of the AA filter has come up numerous times and I'm thinking it won't be long before we begin seeing such things appear in the near future. That being said, I wouldn't obsess over theoretical output at this stage since we have samples to look consider. To which I'd add, the proof is in the pudding(so to speak), as the K-5 II image seems very well positioned to keep-up and in many areas even outperform the K-5 IIs in terms of final IQ which you yourself pointed out, as the effects of aliasing can extend beyond that of the expected color patterns we often see.
At any rate, I agree with the notion that such decisions are highly person dependent in the end. Not to mention that the K-5 IIs has the advantage of producing much sharper images OOC than the K-5 II. However, I also think it's important to put out there that the K-5 II can be processed to match the K-5 IIs in cases where shooters are willing to process their images. And so, it really comes down to what it most important to people in the end I suppose.
