What it is
A one-minute high-speed camera clip of a Nikon D3 shooting continuously at 11 fps, showing the mirror, shutter and aperture blades in slow motion. The Japanese description says the footage makes clear that sub-mirror vibration prevents autofocus from working during bursts, and measures the real rate at 11.01 fps.

The beautiful D3 at 11 fps [this video] It is at 1/4000s so you can see the sync speed, which causes rolling shutter effect and need for HSS. It also shows the lens aperture, though the actuator is out of focus.

One of the decisions Nikon made when Autofocus first became a viable technology on a consumer scale about 25 years ago was to create a system that allowed it to be backwards compatible with the existing Nikon F-mount lens lineup. This meant maintaining a mechanical link between the camera body and lens to stop down to the aperture setting selected on the lens' aperture ring at the instant just before the shutter opens. Since metering and focusing (manual or automatic) are typically done with the lens at its maximum aperture, the amount of time needed to actuate the aperture directly impacts the amount of shutter lag the camera displays. In very cold environments mechanical devices machined t

Rather than transferring mechanical motion from the camera body to the lens via a mechanical linkage (what Nikon calls a regular diaphragm), in order to control the size of the aperture diaphragm an electromagnetic diaphragm uses a small motor inside the lens to move the diaphragm based on electrical communication between the camera and lens. There are a few advantages to using an electromagnetic diaphragm: The moving parts are all inside the lens and protected from potential damage when the camera and lens are connected and disconnected from each other. Nikon's old style mechanical linkage can be bent if the lens is not aligned properly when mounted on the camera and this results in inaccur
