Say What? K10D at 5000 frames a second?

Some very very sexy footage.....
When watching it you start to realise that it looks like you could squeze a hella'ova lot more frame per second out of that shutter box.... (perhaps)


Enjoy!!!

I cannot get over just how much movement there is in everything, the mirror shaking on return and the ripples in the aperture blades.

I know ay? Kind of scary to see so much play in the blades and seeing the mirror bounce nearly halfway back up the shutterbox.....but still i would not have it any other way, I love the sound of the K100D's, K10D's, K20D's, K200D's ect shutters. there so much more reassuring than the sounds of say the 7D

Love that video. That video is part of a series of very impressive high speed shots. I saw one of a camera doing around 8 fps (I think it was a 7D) and it seems there is still mechanical room for squeezing more.

It was interesting to watch this and then compare it to the related similar video of the Nikon D3. Watch the aperture open after the shots from Nikon!!!

Am i the only one who thinks that the aperture stops down to full F22 only after exposure? Like the blades were sticky.
Or is it some movement beyond f22, when it starts to close?

No, if you watch closely, the shutter doesn't open until about five seconds AFTER the aperture closes down. Notice how small the slit is. Remember, it says the K10D shutter speed was 1/2000 second. After the aperture closes, you can still see one of the rivets (or whatever) that attach the shutter blades to the actuating arm at the top of the sensor. This is a dead giveaway that the shutter isn't open yet.

A few seconds later, you see both the leading and trailing shutter moving together from top to bottom. It looks like the shutter opening is less than 1/8 inch.

When I first watched it, I thought that the shutter movement I saw was just the trailing shutter, as it closed. But that would mean that the entire sensor was exposed during a 1/2000 second shot, which we all know (from the 1/180 sec flash sync) that this isn't true.

That was just plain cool.

Wow, yup, a lot of movement. Just goes to show how mirror lock up can minimize that shake.

Nice post.
