Well, moire can be removed somewhat in software. It depends on the moire. Some is much harder to remove than others. Repeating patterns don't often occur in nature with the regularity it does with manmade stuff. It happens but much rarer. If your subjects will nearly always be natural subjects the E is plenty fine. I think if you will be doing anything with manmade stuff then I'd lean towards the non-E.

Yes, that is true, but another thing perhaps to consider is what you intend to do with your images - ie: output them in what form, print them to what size etc.?
I would also suggest that adding acuity to an image through post processing sharpening is possibly easier to do than removing moire over a large area in an image.
I've opted for the non-E because on balance I think it will be more versatile for my type of shooting and, given that I am unlikely to print poster size images, I can possibly "fix" any minor loss of acuity in PP.
Just my pennyworth.

I would also shoot the prom at my wife's school where she teaches each year with it. I am sure my cats will find a place on the flash card as well, LOL. Family portraits and woodworking projects too. It is just mostly landscape and macro, especially of bugs.
Shoot nature with respect and don't trample it or startle its inhabitants.
