Adobe has introduced an update for Lightroom 5.6 that does the usual and also supports, among other cameras, the Nikon D810.
Curiously, I don’t see any indication that this is a beta version, even though just a couple of weeks ago (Ftc 18-7-2014), Adobe released the beta of ACR 8.6 which in principle is the same one that includes Lightroom. Is one a beta and the other one not?
As for me, I wouldn’t trust Adobe even if it were hanging by a nail and burning on the edge of a cliff.
As for you daring users out there, I’ve seen on Canon Rumors where you all can find more details.
And here you can download it:
