I’ll be brief. This is a follow-up video from the prior showing how slow the D600 was responding to using only the USB connction via the Promote Control.
I bought the promote control branded shutter release cable that is used with the D600 and the good news is now things are far faster. This is the same Promote Control shutter release cable used on all Nikon cameras from the D90 thru D7000 which works for all of Nikons mid level (in camera 3aeb) cameras.
The capture speed is far faster now using that with the Promote Control. Video clip below.
