"What's with all the mirror flapping in Live Mode?"



On a D5000 in Live Mode, when I press the shutter, the mirror flips down and back up before the shutter opens, stays up while the shutter is open, then flips down and back up again afterwords. This seems like a lot of unnecessary activity. The mirror is already up; why does it need to come down?

The flip down/up before the picture is really annoying. It makes the shutter lag about 1/2 second, so Live Mode is useless except for stationary subjects. It happens when the shutter release has been half-pressed long enough to get the focus and exposure, or in manual focus, manual exposure - so it doesn't seem like the camera needs to access the metering or phase-detect focus sensors. I have a friend with a D7000 and he says it does the same thing.

Is there a reason for all this? More important, is there any way to stop the pre-picture mirror flip? The one after the picture is mystifying and noisy but doesn't affect the photo, so I'm OK with it.

The reason for all the movement with the mirror in live view is that the mirror needs to be up for the light to hit the sensor so you can view the image on your screen. once you compose the image and depress the shutter all the way the mirror drops to capture the image. It then goes back up to return to live view.

Part of the capture process includes verifying or acquiring focus, exposure, moving the mirror up, open the shutter, close the shutter, drop the mirror. And then open the mirror and shutter for Live View.

The manual does say to cover the viewfinder during live view so the light from it doesn't affect the exposure. I wish it would recognize that it's in manual mode and doesn't need to go through that step. I'll see if I can write an email to Nikon and request that change. With the D5000 out of production there's no chance for a firmware update, but maybe that feature will get into some future model.

I asked the same question to support@nikontech.com. Their answer was that the mirror needed to go down and back up before the shot to "reset" before taking the picture. That made no sense to me, but that was the only answer I got. The D7000 has a mirror lock-up feature, which, if it works like I think it does, may be the answer. I'll get a chance to find out when my D5k wears out in another 92,000 pictures.
