SLR Mirror and Shutter at 10,000 frames per second

It's a digital camera they use, but the mirror and the shutter should be the same on a film camera.

The interesting thing to me is there really isn't any difference in the highest shutter speeds (and probably the slowest too) when you compare the blade speeds, only the size of the slit.

Edit: The video is of a normal SLR focal plane shutter taken at 10,000 frames per second so you can see how the shutter operates. If I could edit the title I would.

I didn't watch the video but... 10K FPS with a mechanical mirror and shutter? Mmm... I have my doubts.

I don't need to watch the video, it isn't possible to raise and lower a mirror that size 10,000 times a second - and that's forgetting about making an exposure after the raising and before the lowering.

I was trying to be nice.

I wasn't. Utoob gives me the $hits all too often.
But, there's some really great stuff there as well.

It's amazing how much things flex. You can see waves travel thru the leafs of the shutter and the mirror bounce. I also like the illustration of the rolling shutter and the cork popping.

Thanks for the link!

It was the camera recording the firing target shutter that was exposing at 10,000 fps. Not the target shutter itself...

Pretty cool video.

Hulcher high speed cameras are capable of these kind shutter speeds but they use a rotary ahutter.

Contempt before investigation and all that rot you know.

With Utoob who needs fiber?

Oh it wouldn't be APUG without the kneejerk contempt, surely?

The header is misleading. Instead of 10,000 frames per second, it should be shutter at 10,000th of a second.

The camera filming the Canon DSLR shutter uses a frame rate of 10,000 frames per second.

And the Canon's peak shutter speed is 1/4000 second.

Actually, the fellow making the video explicitly states that the target DSLR shutter has a minimum speed of 1/8000 of a second...
