I guess time could be a BIG factor.....perhaps 2 seconds Vs. 25 seconds.
But with a Decent/Steady tripod, does the mirror movement really cause that much concern.?
Thank You
The old photo magazines tested this. For long exposures, the mirror induced vibration is such a small part of the exposure that any effect is minimal. It's been so long, I don't recall why there would be much vibration if the camera is on a sturdy tripod - maybe the mirror bounces?
