It's a fact there is no mirror lock-up on the Bronica SQ, but it seems to me there is a slight (and audible) delay between when the mirror flips up and when the shutter fires. Am I nuts, or is this real? If so, is the delay sufficient to reduce camera vibration related to mirror slap? Just wondering...

There is always some delay between the mirror flipping up and the shutter firing in any SLR, so you are not nuts. I vibration is a problem (and I have never heard of issues with the SQ system), you can always get an SQ-A or Ai body, which offer that feature.

Not sure vibration is a problem, but I’ll find out when I develop my current roll of film (still in camera). It has several natural light portraits of my daughter shot at very slow shutter speeds, like 1/15th sec.

When you release the shutter on any SLR with a "between the lens" shutter, the following has to happen:

1. Shutter closes to keep light from entering the camera via the lens..
2. Mirror goes up to keep light from entering the camera via the viewing screen.
3. Shutter opens, then closes, to make the exposure.

If 2 happened before 1, you'd get inaccurate exposures.

It all happens very fast, and most people don't notice the sequence--I certainly don't, but it does have to happen that way.
