May I know the camera raw version you have in Lightroom ?
As to support Nikon D610 and 810, the version of Lightroom required is 5.6 and camera raw is 8.6 (Cameras supported by Adobe Camera Raw)
If you are talking about the Adobe Camera Raw supporting Photoshop then please help us with the version of Photoshop you are working on.
i pay PS once a year thats up to date cs6 .. my LR is 5.7 ... i just thought different as the d610 and d810 have different
ACR 's but both within the same LR .. so i'm ok ... lR 5.7
If you are paying for Photoshop once a year, it seems to me that you have subscribed to the creative cloud. If that is the case, why are you still using Photoshop CS6 and Lightroom 5.7? There are newer creative cloud versions of both programs that you are paying for but not using. Or, am I not understanding your situation?
