The idea behind the statement: I'd expect the down sampling to generate more blur than the anti aliasing filter ever did. The tool you have to recover the blur is just sharpening.


I'd be surprised if you saw a difference. Remember, the image has to go through a re-sizing algorithm that would cause the slight difference between an AA image and non-AA image to disappear.


The effect of omitting the low pass filter decreases as resolution increases. That's why we're suddenly seeing AA filterless cameras, we've reached a point where aliasing is no longer a significant problem. The difference you see will depend on what glass you're using, really sharp lenses will still produce aliasing, at least in the centre. In most cases ...
