As we know Nikon cameras do not have a Quartz controlled clock so every week I have to re set the clocks on 4 cameas so they will sync for lightroom.
If I plug in a GPS unit does it reset the camera clock to match the GPS and is there a GPS unit that will work with the D7100 and D800? Maybe with two cables or an adaptor.
I just want to plug it into each camera for 20 sec to set the clock ..is that possible?
( dont tell me I can adjust clocks in lightroom I know that I want my cameras in sync)
