I'm curious what your sharpening settings are as owners of D800e who use Capture NX2 for processing. While I will vary the sharpening to suit a particular image, I have always found with most cameras that there is a good base setting that will work for most images.
First off, I shoot with a modified Standard picture control with contrast boosted to +1 and sharpening set to 6. (As opposed to the unmodified Standaard picture control with contrast at 0 and sharpening at 3.)
What I have found works for me is to apply USM in CNX2 at 100% intensity, with a radius of 1 and threshold of 1. This is much different thatn my D3s or D300s (or even D700 or D700 when I had them), where a much lower intensity (35-65%) and higher radius (3-5) and threshold (1-3).
