For those that stubbornly cling to Nikon software, Capture NX2 Ver 2.4.5 is available for download.
I have skipped the last couple of updates but after reading the release notes on the new version I have installed it. Apart from the usual new camera body and lens support additions the program now has an updated noise reduction facility. Separate sliders for chrominance and luminance reduction and sharpening are now in place. Seems to work quite well.
