In terms of animals, the algorithm can recognize cats, dogs and birds, while the vehicles setting knows how to home-in on planes, trains, bicycles and motorbikes. Like the Canon, the Nikon has been trained to recognize eyes, faces and torsos, so that it can maintain focus on the same person, and focus in on the most relevant detail. The Z9 has been trained to recognize a similar range of subjects to that of the Canon EOS R3, with humans, animals and vehicles all capable of being prioritized by the camera. Just as 'Stacked CMOS' has become the key hardware change underpinning the latest generation of pro-grade mirrorless cameras, subject recognition algorithms trained by machine learning is proving to be the defining software advance. Our early impressions indicate that dynamic range is just under a stop behind the Z7 II.

This makes it likely that the design of the photodiodes themselves is very similar, but with more sophisticated readout circuitry. But, just as excitingly, it has precisely the same pixel count as the sensor used in the Z7 cameras, along with the same base ISO of 64. The sensor delivers the fastest readout rate of any full-frame camera we can think of, resulting in a flash sync of 1/200 sec (as fast as many mechanical shutters can manage). But that initial reveal didn't make clear how ambitious a sensor it would turn out to be. Nikon had said some time ago that the Z9 would be built around a Stacked CMOS sensor, with all the speed benefits that brings for burst rate, readout speed, AF updates and video performance.

Nikon becomes the third brand to build a pro-grade mirrorless camera around a fast-readout, stacked CMOS sensor, and seems determined to show that has no intention of being an also-ran as the market moves to mirrorless. The Nikon Z9 is a 45.7MP full-frame pro sports mirrorless camera: a high speed, 8K-shooting statement of intent from one of the industry's biggest players.
