5D Shutter in Slow Motion

Fun
Here’s a vid of the 5D shutter in slow motion. Apparently shot at 2000fps using a Phantom HD.

when the mirror goes up and down, is it suppose to bounce around like that? wouldn’t it cause some darkening on the top portion of the image?

No, the shutter only opens after it goes fully up and has already closed by the time in bounces at the end. The sensor is only exposed as the curtains open and close. :-)

That is a 5D that has a relatively slow fps. Imagine what it looks like for cameras that hit 11 fps or better… Wow. I guess they have to control that mirror bounce.

The neutral observer thinks it would have looked the same. In his opinion, the neutral observer believers you are thinking about shutter speed, as in the minimum time the shutter can expose the sensor (or film), and not frames per second.
Incidentally, the neutral observed looked it up, and the fastest shutter speed on this camera is 1/8000 of a second, which is one of the faster ones out there.

The Neutral Observer is missing Dude’s point. It is not the shutter speed it is frame rate. If the frame rate is 10 vs. 5, that whole sequence would have to happen twice as often, which means there is less time for mirror bounce, etc.

1/8000 s is immaterial to the issue of mirror slap etc. The short time is achieved by running the 2nd curtain right after the 1st curtain, separated by a small distance. It still takes approx 1/200 s for the curtains to travel from top to bottom.

I just hope you realize the mirror bouncing doesn’t happen between frames at 11 fps. During bursts the mirror just stays up until the burst of frames finishes, so the only part moving would be the curtain going up and down.

Exactly, no reason for the mirror to bounce up and down, say in video 30 fps. Just leave it up.
Easy to verify – does the optical viewfinder blank out during video modes?

Zac Reply:

you know it does because movie mode is a variant of live-view capture, during which the mirror is locked up.
also a 35mm mirror assembly can’t survive 30 fps anyway.

DeeWee, in motordirve the mirror returns after everyshot so the camera can continue AF tracking.

Now you know where all that camera shake comes from when the mirror isn’t locked up!

cool vid! thanx.
and yes, would be nice to have a similar vid of a succession of 3 or 4 exposures with a 10fps cam, and with the time displayed. :-)
cheers

quite a lot of vibrations going on there. I wonder whether it wouldn’t be better to slow down the mirror when it reaches the open position instead of forcing it ( causing bouncing ) … ?
Nevertheless very interesting :)

Now imagine that an attempt at focusing is made each time the mirror comes down! Could bounce be part of the reason for our hit and miss rate? Lens focus speed is probably the dominant factor.
Physics puts a ceiling on the realistic fps that can be achieved, so perhaps the ability to shoot video at full resolution will one day obviate the need for pushing mirror-flopping fps to insane levels (you could argue we are already there… ;-).

Yeah, with the micro43 line they’ve already rid themselves of the mirror. I like where the DSLR’s are heading with the mirror lock up for Liveview better myself. I like looking through the lens optically for stills though they have a ways to go getting the Liveview up to par for video – I have no doubt it will get there in a body generation or two.

Camera manufacturers try to control the bounce, its a trade off for fast FPS. To get the mirror moving faster, it must be balanced, and have low inertia so that force to move it is minimized. These features also increase morror bounce.
The Canon 1D series cameras have a active mirror control, which works via a hook on the back of the mirror to hold it in place when it flips down, reduces mirror bounce and viewfinder blackout time, letting the camera resume focusing and metering measurements more quickly.

That’s true. Of course the 5D series was not meant for action/sports like the 1D so perhaps it’s a question of targeted design.

OK the mirror slap is pretty obvious. Why release this video? Does it mean the new cameras will have a Pellicle Mirror that doesn’t need tomove so vibrations are virtually eliminated and the frame rate can be faster??? Maybe I am just dreaming.

Someone with a 2000 fps Phantom HD video camera wanted something to shoot. Why they don’t shoot something better like a direct print button god only knows!

It’s incredible to imagine the sort of engineering that has to go into these devices, the speed of the components and the stresses they must undergo. We simple laymen just don’t appreciate how impressive it really all is.

At some point, an electronic shutter will replace the mechanical one. That by itself doesn’t address the mirror bounce, though.
