I'm debating the relative merits of the D800 vs. the D800E for landscape photography and am looking for clarification on something that's puzzling me. I've read more than a few places online that if you're going to shoot at smaller, diffraction-inducing apertures, you might as well get the D800 because you're negating the sharpness advantage of the D800E. It seems to my logic that the loss of sharpness from the OLPF in the D800 would compound with the loss of sharpness from diffraction such that, under identical levels of diffraction, the D800E would still produce a sharper image than the D800, all things being equal otherwise. If the main drawback of the D800E is the risk of aliasing/moire, and the smaller apertures common to landscape photography for maximizing DOF help to reduce or eliminate moire, wouldn't the D800E still have an advantage over the D800 for landscape photography by producing sharper images, even if they aren't optimally sharp due to diffraction? What am I missing? I realize moire situations are relatively rare in landscape photography, but barn shingles and wave patterns in sand dunes are two examples that come quickly to mind. Thanks in advance for any input. I've already pre-ordered the D800 but am wondering if the D800E wouldn't be the better choice for use almost exlcusively in landscape photography.
