Liveview isn't so good after dark, at least on my Nikon D810. It's often difficult/impossible to tell if something is in focus.
If I have my camera on a tripod for an hour or two, is there a way to record manual focus during the day, then reproduce the settings accurately at night? The focus scales on my lenses don't seem like an incredibly accurate way to do this.
I think after the SDK comes out for the D810, digitally will be the best way to do this for lenses with AF motors, but I'm curious if there is some other trick? I was reading about how cinematographers use external focus controls sometimes?
