Recommendations:
1. Remember that exposure will be calculated before the
mirror goes up.
2. Likewise, flash exposures are calculated before the mirror
goes up, so you’ll see a preflash on pressing the shutter
release, then the main flash one second later when the
shutter opens. For most subjects, that is probably okay,
but be careful of subjects that will be startled by the
preflash. Some people will blink in response to the
preflash and have their eyes closed at the main flash.
Some insects and animals will bolt on the preflash.
3. In general, I prefer this function to the
M
UP
frame rate
function only when I’m handholding the camera and not
using a wired remote. The timed shutter lag also works
best for static subjects (some people and animals react to
hearing the mirror flip). I use
M
UP
when my camera is on
a tripod, using a remote release, and trying to precisely
time the actual picture taking for a particular moment (e.g.
in macro shots trying to time when the wind stops
blowing the flower).

Previous Nikon bodies used a delay of 0.4s, which in extreme cases didn’t quite
wait long enough for support system motion to dampen due to the mirror slap.
