The article includes this statement (bottom of page 3):
"Stop the lens down about 3 f/stops from its maximum aperture. This requires you to shoot around f/5.6 or f/8 all the time. Stopping the lens down to a smaller aperture (such as f/11 or f/16) will cause diffraction to lower the sharpness, reducing the benefit of the OLPF. This will easily negate the benefits of the D800E."
If this statement is correct it seems that the D800E will not be the best choice for landscapes since most landscape photos will be made at apertures of f/11 or smaller. I note that in this article Nikon lists studio, commercial and still live photographers, but not landscape photographers, as the “…few specific type of photographers” who can benefit from the D800E (page 2 of the article).
I am among the many who are trying to decide whether to buy the E model or the regular model D800. I have been leaning toward the E primarily because I thought the added resolution would be a good choice for landscapes. However, it appears that this is not correct and that the advantages of the E model may be more limited than I had understood. I realize that Nikon is trying to warn us of the limitations and possible drawbacks of the E model in order to limit the number of complaints when E shooters experience these problems. However, the quoted statement is quite specific and I know of no reason not to accept it as accurate.
Please provide your opinions about the use of the E model for landscapes and my interpretation of the Nikon article.
