Shutter sounds

In live-view the mirror is up, but when you take pic you hear loud shutter just like if it was not live-view, so it appears the pic is taken and then the camera flips the mirror down and back up just to make a sound. Seems silly to do that.

The mechanical shutter is still necessary during live view. When you’re prepping your photo in LV, the mirror is up and the shutter is open so you can see the sensor readout. When you take a photo, the shutter closes and then rolls over the sensor in order to expose the image. This is why you still hear a mechanical actuation in LV. 🙂

The reason the shutter is necessary is because the sensor in the SL1 is not capable of what is called a global shutter which, allows the sensor to determine its own exposure free of the mechanical shutter.

Hope this helps!

Ah, getting better info.

I now see that in LV mode the only way it shoots is in silent-shutter mode, even if non-silent is selected.

There are no other options on SL1 for silent-shutter settings (like there is on 5D), on or off are the only two I see. It does sound like shutter closes, wipes, the resets back to LV. This probably explains the ~72msec "shutter-lag" I see.

As far as "global shutter", doesn't it do full electronic shutter when in video mode?

Any way to make shutter-lag less?

It also seems to be the case the when not LV mode, silent shutter on makes the mirror move more slowly, I can see the slowness in the eyepiece. When not in LV and std shutter, the flip in the eyepiece happens much faster, and I guess that means more sound as the mirror bangs at the end of travel.
