Indeed, working with that kit every day (Phase One) Oh how I pray for the day when we can get interchangeable camera backs for DX and FX DSLRs.

Does anyone care about moire?

Real estate and you actually care about image quality?? You'll be the first I've met that does. Congratulations.

I think this is a point that few mentions:
The moire/aliasing that is present in a (sharp) system with no prefiltering can affect low-frequency output, the kind that is visible in smaller prints and/or at larger viewing distance.
The loss of sharpness attributed to the OLPF will only affect high frequencies that (for large pixel counts) really only matters for pixel-peepers or really large prints viewed up-close.

For analyzing such images, it would be really helpful to have two separate shots of the same scene with as few changing variables as possible. Minute random changes would cause the sensor to capture slightly different "phases", and it would be easier to tell what is aliasing, and what is true detail.

The techies/pixel peepers praise it, most photographers realize in their normal output this "increased resolution" isn't visible. I posted in another thread in an 8X10 print (and even up to 11X14 for most subjects) I can't see any real increase in visible resolution between my 5MP olympus E1 and a D7000. The reason I got the D7000 wasn't for the resolution, it was for the high iso/DR performance gain.
I can understand if people are looking to make wall size prints all this would matter. I also believe very few photographers images need or should be printed that large. If an image isn't striking at 8X10, blowing it up to 8X10 feet isn't going to fix it
Moire can occur on cameras with OLPFs and it can occur on cameras without OLPFs. See this Olympus EM5 vs Nikon 1 V2 comparison below. Since the V2 does not have an OLPF you would expect loads more moire, but in fact, it's the EM5 image that has more instances of moire (click on image, then click 1:1 to view them full-size). The white building with blue lettering on the right side of the image and the small blue tiled building in the center / right of the frame.
Notice that this EM5 image actually has more instance of moire than the Nikon 1 image below (click once, and then click 1:1 to see at 100%).

The Nikon 1 camera which has a 14 mp 1" sensor and no Optical Low-Pass Filter
Depending on what you shoot, for general subjects (nature, portraiture, street photography, sports) the increase in accutance that you get with many of the latest cameras without OLPFs (Leica M9, Coolpix A, D7100, D800E) is well worth potentially more moire in certain situations. And since moire can occur with all high resolution cameras with or without OLPF, there is simply no reason to prefer a camera with an AA-filter vs one without.
A look at the DPR Coolpix A Studio RAW samples (See link below) show that it indeed is out-resolving other 16 mp cameras. Will you get moire with a Coolpix A? Perhaps. But this is true of many other cameras as well. But the benefits of sharper images, far outweigh any perceived disadvantages of occasional moire.
DPR Coolpix A Studio Comparison (RAW)
I have a Nikon D800 that is by far the best camera I've ever owned including my 5D Mk II. But if I had it to do all over again, I would have purchased the D800E. The D800 with the Nikkor lenses that I use produces highly detailed files that I couldn't be happier with. But since I'm not a professional, a few instances of moire here and there are simply not a big deal. Besides, both D800s can produce moire in certain situations, so there is almost no reason other than price to prefer the D800 over the E.
Cheers, and happy shooting,

It's hard to believe that anyone would paint pink and green stripes on a building, so yes, it must be moire.
And I find moire pretty common when taking pictures of buildings.

Svalbard, eh? Must be some good photo opportunities in and around that area!
Here are four crops from the Imaging Resource raws. I would submit that the D7100 and the D600 are resolving more and have better sharpness than the D7000 and the D5200, however you want to spin the English language. If one applies a blur filter, one is by definition resolving less.
As well, the D7100 has higher contrast and richer color than the D5200, no contest (same settings.) Right there in all departments except color intensity by a nose with the D600, which is a feat in itself.
If any of you feel you can make the D5200 look as good in any way whatsoever than the D7100, I hereby challenge you to do so. I also challenge anyone to provide proof of "false detail" or any other harmful artifacts. Theoretical blah blah blah isn't going to cut it, only pictures or it didn't happen.

That's probably because the kit lens isn't nearly as sharp as the Panasonic 25 1.4.

there are ways to deal with it if it really affects the shot.
