Originally posted by Canada_Rockies Agreed. But to reduce moire, you don't need to mix all four together to the same extent as the AA filter does. You can select the degree of blur to just barely remove the moire, and only in the area of the image where it occurs, and thus retain more detail. More detail is what I want. I shoot a lot of birds at great distances, and cropping can be done to a greater degree with more detail retained. I also shoot a lot of scenery, and greater detail can mean more realistic images.
Indeed you can be specific with removing the moire but you need to blur more though then the AA filter does.
AA filter blur is about 1 pixel or so right? if you blur that much with a blur tool you are basically mixing pixels for 50% it reduces the effect but it's not enough to remove it. It's already some time when i had to use it so can't remember but it wasn't a low value.
Beside that there are kinds of moire like pattern moire that are harder to remove.
The S version does a good job though and often it's not a problem at all but you do get more moire with it then with the normal version.
As for sharpness and greater details, when you're comparing unedited files there is indeed a difference but when edited you need to look good to see the difference at 100% zoom so therefore i don't believe there is a difference you can normally see.
Unless you don't edit your images of course, but if that is the case then going with the normal version would be better, slightly less sharpness is less off an image breaker then moiré if you ask me.
