It stores a value. If you turn off SR and turn the camera off and then turn it back on, it does not prompt you for FL. If you go into the menu where you can manually dial in the value, you will see it is greyed out. If you turn on SR again, it will be a valid menu option once again that you can dive into and change the value. It just reverts to whatever value was input previously. If you swap lenses without turning off the camera, that value will just stay in there because there isn't any communication with the lens at all other than maybe aperture if it is an A lens. Does that make sense? The camera only really cares about FL on manual lenses when SR is turned on. If you're doing long exposures and not using a long lens, you could probably get away without mirror lockup or a timer if you used a remote. Just like the good old days. The mirror is very well dampened its been proven that during excessively long exposures (over 1s) mirror lockup has no impact at all.
