Which brings us to the moire reduction in PP... it can't be done reliably for anything that is not near-monochromatic in nature.

People tend to bandwagon hate on things... AA filters are just another helpless victim. They do far more good than people give them credit for. Except in cases where they are overly strong in order to mask noise.
I agree. however I might add to that, since switching to MF and with the lack of AA filter I have significantly greater usability from cropping.

I think one of the things many people did appreciated with the older 1D series (1Ds2 and below) was the 'not as strong' filter. Personally I found the 1Ds3's filter a little on the strong side, but was more likely due to the increase in resolution. Once you start working without one, you build a stream, plus with consideration to the tools now available, the ease of removing moire has been greatly improved.
Personally I do want to see a move to a removal of the AA filter on the pro lines. It's not likely to happen, but doing so we'll see a significant boost in the usable resolution of images, on the other hand, the quality of glass will take on new meaning. The faults won't be exaggerated, but they will become more obvious.

Isn't that kinda like using two different lenses, (one good one and one soft one), and saying that the images will have negligible difference after sharpening?

Agree on the moire trade offs though and it's always a balancing act for designers in selecting an AA filter that gets the best micro detail out of a sensor without introducing moire.

It shouldn't be. AA Filters are optical low pass filters that work in pairs along the horizontal and vertical imaging planes. As opposed to a lens that is simply blurry in a radial pattern.

Yeah true about the imaging planes. I recall an older DSLR that registered extremely high extinction scores on one plane and only average scores on the other. It kicked off a fair bit of discussion at photozone at the time. Still though, if fine detail isn't recorded at the time of capture then it's always gonna be a struggle to bring it back regardless if it's due to a soft lens or the presence of a strong AA filter. I guess we'll see how the AA filter impacts the new Sony sensor once the D800 is released.

I don't think most people will complain with the idea that the D800 will allow you the option.

Coming from a D700 and all my previous bodies having AA meant I had no option to begin with, so this is a bonus in any regard.

Only a week to go now, i'm getting excited. Just bought a whole heap of lenses to play with

Yeah I agree.

I like the idea of customisable bodies be it focusing screens, locking mode dials or body grips. AA filters take it one step further and I hope more manufacturers follow take note and follow this trend.

Because most of us are in the same position as you re AA filters, the D800 minus the AA filter may end up the better seller.

Needs more buttons, protrusions, and gold lettering IMO.

Yeah, plus it needs a 'Coffee button', and c'mon... it doesn't even have a teleport button.

Interesting that the official blurb references wedding photographers. Knew the resolution would appeal, but obviously they think it can handle the high ISO demands as well...

I reckon the lines are straighter, like the D7K.
Although the curvy D700 would probably be nicer in the hands I like the new shape.

It does not look like a Canon!
