im just new here, but I want to show you some Videos I made a few weeks ago.http://frari-art.de/spiegelschlag-und-blendenlamellen/
Here you can see the Mittor of a EOS 450d DSLR in HighSpeed and the Aperture of an EF 85/1.8 Lens.
The Mirror Video was taken at ca. 6.000 fps with an Time of 1/160 Sec.
The Video fpr the Aperture was taken at 6.000 fps with 1/4000 and a Aperture of 22.
The Original Videos are just 0.6 seconds and take about 5GB each Space on the drives.
Hope its interesting for you!
