As predicted, the Z7 is still completed to the same high standards as Nikon's DSLRs.
One of Nikon's promises when introducing their first full-frame mirrorless camera duo is that they will be solidly built, sturdy, not inferior to their previous DSLR products. And recently, the infrared camera making website (converted from conventional cameras) - Kolari Visio has bought a Nikon Z7 to perform a teardown, and verify this claim.
In reality, holding this camera in hand is no different from holding a DSLR because it is very balanced, and even when disassembled and reassembled, there are no loose components creating annoying 'clicking' sounds. The company also claims that the rubber gaskets protecting the connectors, and the XQD card slot are very weather resistant.
If not for the new Z-mount system, Nikon could completely call this Z7 a 'weight-loss' version of the D850, because although it has a mirrorless design, in reality, this camera is as sturdy as previous DSLRs.
Similar to the Sony A7RIII, the bottom of the camera is the first part that can be removed.
Then, we will unscrew the screw holding the battery grip in place.
There are also a few small screws on the side with the connection ports.
Next to the electronic viewfinder are another 4 screws.
And finally, there is a screw right next to the XQD card slot. We really have to be strong to unscrew this one, as if punishing the camera for not having 2 memory card slots!
To remove the camera frame, we need to peel off the leather layer on the grip.
The camera's circuit board has many new connection pins, unlike previous DSLRs. A strange point is that the Z7 does not have a cooling system like Sony's cameras, is this good news or bad news? If the camera does not overheat in real-world use, perhaps Nikon has designed components that far exceed their compatriots, otherwise, the company may have made a mistake by not adding cooling!
By unscrewing this yellow-colored connection leg, we can remove the LCD screen from the camera.
By unscrewing a few more screws, we can also remove the camera's circuit board.
Below, we can see a 'nest' of bright yellow connecting wires. Gently pry these wires, continue unscrewing to remove the camera further.
We will examine the circuit board closely, some of the connection ports at the top are definitely new, never seen on other camera models!
On the back of the circuit board, we can see the XQD card slot. The company must have thought very carefully when choosing only 1 XQD slot or 2 SD slots. Sony's A7RIII and A7III products have 2 SD slots, and their slots are also made very thick like this. Nikon chose XQD cards because they believe it is more durable, 'accepting' both regular SD cards. Perhaps when the camera is widely available, many users will only then know which one is better!
Some macro images of the camera after being 'stripped down'.
The Z-mount can be removed after loosening 4 screws. Just below the mount, there are a few small rubber seals, perhaps to prevent water and dust.
The camera's diopter adjustment dial... also has another screw.

Now we will move on to the most important component of the Z7: the 46MP Full-frame sensor, supported by the IBIS stabilization system. This sensor is held in place by many screws and springs, to ensure the most accurate focusing and image capture.
Right next to the sensor are the headphone and microphone ports, similar to the Sony A7R III.
This is the sensor along with the IBIS stabilization system.
When lightly pressing on the sensor, Kolari Visio found that the IBIS system does not move as much as Sony's cameras. However, according to the company, the Z7 still provides 5 stops of stabilization according to the CIPA standard.
Another interesting point is that the protective glass layer for the Nikon Z7 sensor is only half as thin as Sony's sensors, at only 1.1mm. In theory, the thinner this glass layer is, the higher the optical quality with adapted lenses from other manufacturers. Kolari Visio notes that users can replace this thin glass layer with one that is only 0.2mm thick if they prefer!
This website will also convert this Nikon Z7 into an infrared camera like many other cameras!
After disassembling the Nikon Z7, the company believes that this is an excellent camera from the inside out, with components integrated tightly, and arranged in a 'learned' manner from Sony. But is this the new standard for mirrorless cameras in the future? Perhaps only time will answer this question.
