With nothing better to occupy my mind I’ve been customising the controls on my Nikon D810. Having owned the camera for nearly 5 years you could say it’s a bit late. There are only a few settings I regularly change but assigning them to buttons on the camera negates the need to go into the menus and does indeed speed things up. Rarely shooting anymore the only problem I foresee is remembering which functions I’ve moved and to where.
