Ahhh, ok, relying on AF makes much sense now in your case!

@lordsmurf, but wasn't the LP filter put there to remove Aliasing in digital sampling, and that the removal of such, even if it allowed greater perception of sharpness, ALSO removed protection from moiré? How might they be getting around that?

How many hoops is someone willing to jump through....how many workarounds is one too many before a person realizes that they may have the wrong tool for the job?

A few years ago I submitted footage for a concert intro video(people clapping hands to a song). 3 or 4 of those clips ended up in the footage that was shown before every show to thousands of people (each night) for many weeks of the tour.
The videos clips were shot with my Canon Ixus 90 portable, and the guide music used during the filming was played on my iPod Touch.
I still have all of the original footage. It's just a shame I wasn't there to see it in person.

There's a direct relation to the megapixels (35+) and the sensors (Bayer method). At some point, AA filtering will not be needed. Only the IR/UV blocking filter will be needed.

One of the Nikon (D800E) has no AA filters already, but the issue is moire on the video. The downres processor inside is too stupid, and needs to be better to be useful. The video it shoots is almost a step backwards in quality time.

The still photos have it as well, as the sensor is Bayer. You get sharper images with the D800E, but you have to process to remove a fairly consistent moire. Internal JPEG appears to already fix it. I've seen a few JPEG samples, where the person was trying to get moire, and it looked sharp as hell. I've seen mixed reviews on the RAW. RAW may or may not fix it -- but that's RAW for you.

Look at this: http://www.luminous-landscape.com/reviews/cameras/nikon_d800_d800e_first_comparison.shtml

KR has a few D800E samples. And while he never explicitly mentions seeking moire, it should be obvious that he is. http://www.kenrockwell.com/nikon/d800.htm

The D800E is also 2 years old now, with R&D at least a year back. So I tend to wonder what's next.

I'm surprised that Bayer is still the method of sensors, as that's what causes the moire. I remember Fuji, Signa and Olympus both had developed non-Bayer methods ... but then I heard nothing more about it for many years now. Foveon (Sigma) was one of them, but had its own drawbacks.

I always wonder this myself. Many times, the arguing you see online is from somebody trying to use something that's not the right tool. Like hitting a nail with a screwdriver. The older I've gotten, the more I tend to just buy the right tool, rather that trying to halfass it with the wrong one.

I've always been this way -- but when I was younger, sometimes I'd at least try the stupid method first (and it'd usually fail). Then I could justify the buying to myself. I don't need that middle step anymore.
