According to the Adobe LR tethering list my camera is supposed to be supported for tethering since ver 5.5. I have tried and tried with zero luck.
Somewhere I saw a post that said to try the manufactures tethering software, well Nikon wants big bucks for their software. One of the reasons I bought this camera was to use it tethered with LR.
I found a freeware program called DigiCamControl and it works great with my D5300 and my old D70s in tethered mode!
I have double checked and there are no software updates for the D5300, I have used three different usb cables, all work with digCamControl, but LR is still saying "no camera connected".
So ADOBE what's the answer to this problem?
