Cameras with no AA filter will inherently have more detail in their images.

This is not true. Camaeras with no AA filter may give the ´╗┐appearance´╗┐ of more detail, but in fact what you see is artefacting, not detail. With a bit of luck, the artefacts might make a convincing representation of detail, but it still isn't detail.

Bob,

would you consider blur to be an artefact? If yes, one is trading one artefact for another. And since sharpening can partially compensate the effect of an AA filter and blurring can partially compensate the artefacts of discrete sampling (ie, with no AA filter), you are a bit more stuck on the blurry side with an AA filter and a bit more stuck on the artefact side without one.

Although I am not Bob I understand the point he is making. In a brief -

unlike the artefacts, you are never stuck on the "blurry side" which is the difference.

If you follow the link in my post, you will see that you cannot fully recover detail with sharpening on a sensor with an AA filter.

The link doesn't show that. What it shows is that you cannot replicate the sub-Nyquist response of an AAless sensor by applying that sharpening function to an AA equipped sensor (strictly, it doesn't even do that, it just shows that Marianne failed to do it, which isn't the same as proving that it cannot be done). In theory, had Marianne applied a sharpening function that was the exact complement of the AA function

And is this an option in reality? Do we know AA function exactly and does have LR a tool where I can input the parameters of the AA function?
