So Nikon does not have a solution and most of the other camera makers like Canon. Fuji. Olympus. Sony. They all do not have a real solution.
......
Nikon did, but seemed to follow in other manufacturer's footsteps then.
CNX-2 for me was more than enough more often than not.
(my only major gripe with CNX-2 was the lack of a proper clone/heal tool)
CNX-D would have been a great upgrade for ViewNX2, considering the more plentiful tools CNX-D offered compared to VNX2.
So for Nikon to announce CNX-D as the successor to CNX-2 was a major step backwards.
Then they announced the replacement for ViewNX2 a short while later, which is now ViewNX-i. (I think the i represents the idiot in idiots edition!)
This was another 2 steps backwards .. which makes for at least 3 steps backwards from Nikon from the point of view of software support.
My major gripe with Nikon's new software solution, is that of tagging raw files via the IPTC framework.
Where CNX-2 and VNX-2 added IPTC/keyword tagging into the NEF file(among other data that could be added later) .. with CNX-D, you can't add any embedded tag info at all .. and ViewNX-idiots edition only adds tag info via it's proprietary sidecar file system only.
And as others have mentioned, CNX-D is slow .. sorry make that verrrrry slowwww!.
Prior to my update to Win10, on Win7 I could only get CNX-D to actually run every 10 or so attempts to make it so via the click of it's exe icon.
All 9 other attempts would cause a crash of some cryptic beginnings .. appdata crash with no meaningful info. Then when it did run, it was slow.
Now at least it does run, but not that I want it too, as it's even slower now on Win10(I feel).
I've tried very hard to like LR(v4 at the moment) but still have a (philosophical) issue with the way it's workflow begins.
I have my own system for tagging cataloging, and don't need LR's obstructive input.
Otherwise I'd take the time to use LR more and more, I've tried a few others too, C1, which was nicer to start with, but not 100% enamoured with the total output quality. I reckon I may learn to massage that tho with time.
So I've decided it's easier to just not update the camera to a newer model ... until I finally decide which software I'll end up migrating too(if I ever do).
It's easier this way .. less time wasted with a chore I don't particularly like much anyhow(PPing).
