Nikon has released its third—of four—teasers for its upcoming Z9 mirrorless camera system. In this latest teaser, Nikon shows off the sports-oriented autofocus and hints at the frame rate of what will be Nikon’s flagship full-frame mirrorless camera system.

The video comes in at just 28 seconds and unlike the previous videos, wherein Nikon showed off the body of the camera, this new teaser focuses, quite literally, on the various AF modes this camera will offer. In addition to an Eye AF mode, which appears to have little problem keeping up with athletes as they’re running around, Nikon suggests that it too will offer a Vehicle AF or Motorsports AF mode, which appears to lock onto both two-wheeled and four-wheeled vehicles.

The last little bit of information we get from this teaser is a continuous burst of shots as a long jumper leaps into the air. Doing some back-of-the-napkin math while slowing down the audio, I was able to count 34 individual (physical) shutter actuations in 1.65 seconds, which comes out to roughly 20 frames per second. It's unknown whether this was a simulated shutter sound for the electronic shutter or the actual sound of a physical shutter, but considering how Nikon stopped the other noise in the video and isolated the shutter sound, it seems clear Nikon wanted us to focus on the sound of the shutter firing away.

A section of audio pulled from the video during the section where a photographer holds down the shutter in continuous capture mode.

We’ve learned quite a bit about Nikon’s new Z9 camera from these teasers and still have one more to go.
