The Z7II is the latest version of Nikon’s premier mirrorless camera. Nikon had been lagging a bit behind Sony and Canon in the full-frame mirrorless game for a while. After all, they didn’t release their first mirrorless camera until 2018, and some have said that things aren’t looking great for them. However, lately, they’ve been catching up and filling out their mirrorless lineup. In fact, as of this writing, they’ve released five new cameras in the last two years—including the Z7II—all of which have been mirrorless.
It looks like they’re learning a lot from their competitors since they’ve built a fairly impressive one with the Z7II. This camera offers 46 mega-pixels, 4k 60fps (with a crop), and is now running off two Expeed 6 processors.
Let’s take a look at what’s changed.
From the front view, the answer is not much. The designers looked at the Z7 and said, “Yeah, that works.” And it does indeed work pretty well. The handling on this camera is quite good and will be familiar for anyone coming from another Nikon camera.
However, there’s one important update that would be easy to miss: the sensor frame was switched from plastic to metal. That means the Z7II is natively compatible with our magnetic clip-in filters for Z-mount; there’s no need for a mag mount.
It’s the same story with the top. We’ve got our standard lockable mode dial; the same LCD control panel displaying the settings; and the ISO, exposure compensation, and record buttons are in their usual spots.
Also unchanged is the port side, which holds the standard array of ports—featuring headphone, microphone, USB-C, and mini-HDMI ports and an accessory port for wired remotes.
Even the back is the same. The EVF and LCD were kept from the previous model—offering 3.6 and 2.1 million dots resolution, respectively.
There is one new feature to note. It looks like Nikon has finally given us a second card slot! Not only that, but it’s an SD card slot. The decision to give the original Z7 only one card slot was surprising, particularly for a camera targeted toward professionals. Whether pro or hobbyist, we think most people would want two card slots for a $3,400 camera (release price). Having the redundancy of a second card slot is vital to most photographers. It means they don’t have to worry about one card being corrupted, and it allows them the option to automatically have a backup of all their files.
Going with an SD card slot was also a good choice. While CF-express cards certainly have the advantage of being faster, many photographers still use SD cards, and SD card readers are far more common, both built-in and external. They’re also a lot more affordable and easy to find in stores. If there was one thing Nikon needed to upgrade—and apparently there was—it was that.
Now let’s open it up and see if anything changed inside.
First, we remove some screws and take off the bottom plate.
We also have to disarm any traps we find along the way, like this battery latch. Those springs will shoot out at you if you’re not careful.
Then remove some screws around the ports and the card slots.
And the screws around the EVF.
Finally, some concealed screws beneath the leather of the handgrip and on the bottom.
And just like that, the back panel comes off.
Already, the interior looks a lot different from what we saw inside the Z7. The two things that stand out the most are the new SD card reader and the metal plate covering the board. That would account for the minor 30g weight difference between the two cameras, with the Z7 weighing in at 675g and the Z7II at 705g.
The plate was likely added to act as a heatsink while adding additional protection to the board.
Let’s take that off and see what’s going on underneath.
This also gives us a chance to look at the weather sealing lining the edges.
Now one of the most exciting upgrades: the new dual processor.
The overall layout of the board hasn’t changed much, which is impressive considering the sizable additions of the card-reader and second processor. Yet, they managed to maintain the same system.
There are a few subtler changes to the ribbons. Some are a bit broader and heartier, which makes them easier to handle and reduces the risk of them tearing while being disconnected.
Next, we’re going to take out the viewfinder. This model features the standard Nikon diopter mechanism, which allows you to lock and unlock it by popping it in and out of the prism. The diopter also features a cap that’s tricky to remove. It serves a dual purpose: indicating turn direction and covering up the screw to make disassembly more complicated.
Beneath the viewfinder, we see a couple of screws that we’ll have to remove to take off the top, along with the many ribbons.
Another interesting thing to note about these ribbons is that some are BIG. We believe the only camera with larger ribbons may be the Z9. Apparently, Nikon likes to use thick flex cables.
Once we’ve removed all the ribbons, next comes the board screws.
And out comes the motherboard.
While we’re here, we’d also like to point out the white cable running across the bottom. This is the antenna cable for wireless connections.
It looks like the frame is blocking access to the sensor screws, so we will have to remove some more of the body before moving forward.
We are starting with the port/front side section, which features the iconic Z7II logo.
We decided to set it on some foam to protect the back while removing the front components.
We’ll also have to remove the lens mount.
Along with the handgrip, which is sneakily secured by a screw tucked away in the top of the battery compartment.
With all that removed, we can reach the screws that hold down the top, allowing us to take that off as well.
Now we’re left with just the core of the camera.
This camera uses springs to calibrate the position of the sensor. The height of the screws is measured in thousandths of an inch and needs to be adjusted with exact precision to keep the focus correct and even across the entire image.
And with that, the sensor is out and ready to be converted to infrared.
This is a pretty chunky sensor with some solid-looking IBIS, but it’s nothing compared to the size of the Z9 sensor, as you’ll see for yourself in the Z9 teardown that’s coming soon.
Thanks for coming to our teardown. Be sure to tip your technicians and remember to visit the gift shop on your way out.
Now that we’ve seen how this camera is made, we will be looking at how well it performs as an infrared camera. We’ll also be doing a teardown of the Nikon flagship, the Z9, and comparing it with the Sony A1.
