These days, camera gear is smart. It’s not just the camera body that runs on software; accessories such as lenses, flashes, teleconverters, electronic remotes, and even battery grips now have their own firmware.
That’s true of many newer Nikon cameras, even some later DSLRs, and it’s especially true of the latest generations in the Z mirrorless range.
The most common code you will see when updating your camera is C. That is the core camera body firmware.
But there are several other types that you might see listed in your menu. You’ll only see these lines in the camera’s menu system if you have the relevant and compatible accessory currently attached.1
Here is a decoder ring for the alphabet soup of Nikon firmware codes:
| Code | Description |
| C | Camera Firmware. This is the main operating system for the camera body. It controls autofocus algorithms, image processing, menu systems, and overall performance. Always keep this up to date. |
| LF | Lens Firmware. Found on Z-mount lenses and some newer F-mount lenses. These updates often improve AF speed, aperture control accuracy, or IBIS coordination. |
| MA | Mount Adapter. This appears if you are using the FTZ or FTZ II adapter. Updates here generally improve compatibility with F-mount lenses. |
| S | Speedlight. This appears when a compatible Nikon flash (like the SB-5000) is attached. |
| W | Wireless Remote. Used for the WR-R10 or WR-R11a/b wireless transceivers. |
| TC | Teleconverter. Z-mount teleconverters (TC-1.4x and TC-2.0x) have their own firmware to manage communication between the lens and body. |
| RG | Remote Grip. Specific to the MC-N10 Remote Grip used for video rigs. |
| L / LD | Lens Distortion Data. Mostly found on older DSLRs. This is a database of lens correction profiles, not the firmware of the lens itself. |
| A / B | Legacy Camera Firmware. On older Nikon DSLRs, the body firmware was split into two parts (A and B). This system has been superseded by the unified “C” firmware. |
| G | GPS / GNSS. Found on cameras with built-in GPS modules (like the D6 or older GP-1 units) to update satellite data. |
If you need to update the firmware of one of these accessories, the process is usually the same: load the file onto the memory card, attach the accessory, and the camera will ask if you want to update that specific device.
How to check your firmware version
Checking your current version is the first step in troubleshooting or maintenance.
Z mirrorless & DSLRs
- Turn the camera on.
- Press the
MENUbutton. - Navigate to the SETUP MENU (the wrench/spanner icon).
- Select
Firmware version(usually the very last item in the list).
COOLPIX cameras
- Turn the camera on.
- Press the
MENUbutton. - Press the multi-selector left to highlight the menu icons tabs, then scroll down to the wrench icon (
Set up) and pressOK. - Select
Firmware version.
Where to find firmware updates
Firmware is essentially the operating system for your camera, and it dictates everything from autofocus tracking reliability to which CFexpress cards are supported.
It is good practice to keep your camera on the latest official release. With the Nikon Z system specifically, firmware updates have been massive, often adding entirely new features (like Auto Capture or Bird Eye AF) that might not have been there when you bought the camera.
Official Nikon firmware updates
There is only one place you should download firmware: the Nikon Download Center.
The official URL is: https://downloadcenter.nikonimglib.com/
(Yes, the URL looks a little weird with “imglib” in there, but that is the official global repository.) You can search by product name to find the latest “C” firmware for your body, or “LF” firmware for your specific lenses.
What about third-party (hacked) firmware?
In the DSLR days, there was a small scene of “hacked” firmware (like Nikon Hacker) designed to unlock video bitrates or remove recording limits.
However, for the Z-mount system, this is largely nonexistent. Nikon’s modern architecture is much more complex and secure. Furthermore, because Nikon has been so aggressive with releasing major feature updates officially (Firmware 2.0, 3.0, etc.), the demand for hacked firmware has vanished. My advice: stick to the official updates. They are free, reliable, and won’t void your warranty.

Batteries (EN-EL15c)
The Z8 uses the EN-EL15c. Always carry spares — mirrorless cameras are hungry.
Top Picks: Nikon OEM (Best) | SmallRig (USB-C Port) | Watson
Memory cards
The Z8 has two different slots. See detailed recommendations here.
- Slot 1 (CFexpress Type B): SanDisk Extreme Pro, Lexar Gold, or ProGrade Digital.
- Slot 2 (SD UHS-II): SanDisk Extreme Pro V90 or Lexar Gold 2000x.
FTZ II lens adapter
Required to use F-mount DSLR lenses on the Z8 without image quality loss.
Notes & References:
- By “compatible” in this sense, I’m referring specifically to compatibility with Nikon’s internal firmware system. Third-party accessories, like a Sigma lens or Godox flash and some newer third-party lenses, have their own methods of updating firmware — usually via a USB dock or USB-C port on the device itself — and they won’t appear in the Nikon menu.
