First, you are correct that I meant "narrow" rather than wide. I have corrected my post to correct my error. I seem to always have difficutly correctly describing the aperture sizes (larger numbers = smaller opening, etc.). Thanks for the correction.
In the article I cited Nikon mentions "studio, commercial and still life" photographers as those who will benefit from the E. Landscape photographers are not mentioned. Have Nikon recommended the E for landscape photographers in another publication? I am certainly not saying that Nikon knows nothing about landscape photography. My comments are based on the statements made by Nikon in the article I cited.
I have tried to keep the topic limited to shooting at the stopped down apertures and not expand it to landscape shooting technique. I agree with you that one should shoot at the widest aperture the shooting situation will allow. I use the hyperfocal tables for that purpose. In quite a few situations the use of f/11 or f/16 is indeed the right aperture. In those situations the benefit of the E is lost, according to the article. If one is able to shoot at f/8 the E does apparently offer some gain in sharpness. Whether this benefit justifies the "cost" (risk of moire in some situations) is the question. For your use you have reached a firm conclusion. I have not yet decided.
