Nikon Zf Sensor Cleaning Function

Dust is the enemy of every mirrorless camera. Because there is no mirror box to protect it, the sensor is exposed every time you change a lens. And with its static charge, it acts as a magnet for particles.

Unlike the higher-end Nikon Z8 and Z9, the Nikon Zf does not have a physical sensor shield (curtain) that closes when the camera is powered off. This makes the built-in sensor cleaning function even more critical for Zf owners.

How to use the sensor cleaning function

The “Clean Image Sensor” feature works by vibrating the sensor at extremely high ultrasonic speeds for a split second, shaking loose dust particles so they fall onto an adhesive strip at the bottom of the sensor assembly.

You can find this feature in the camera menu under:

Setup Menu (wrench icon) > Clean image sensor

Once inside this menu, you have two options:

1. Automatic cleaning

This controls when the cleaning cycle runs. By default, it is set to Clean at shutdown. I highly recommend leaving this setting alone. It adds a negligible delay to the power-off sequence and ensures you start your next shoot with a cleaner sensor.

A Confusing Icon: When you look at the menu, you might see an icon that says OFF next to a camera symbol. This does not mean the feature is disabled. It is Nikon’s way of indicating “Clean at OFF” (shutdown).

2. Start now

This runs the cleaning cycle immediately. You will hear a tiny “zip” sound, and the camera will display “Done.” Use this if you notice a dust spot while shooting.

Things worth knowing

• It’s not a cure-all: While effective for loose dry dust, ultrasonic cleaning cannot remove sticky pollen, oil spots, or condensation. For those, you will need a wet cleaning kit or professional service.
• Use a Blower: Because the Zf lacks a sensor shield, I recommend carrying a Rocket Blower. A quick puff of air before changing lenses is far more effective than relying on the camera’s vibration alone.
• Hold the camera upright: When you run the “Start Now” cleaning manually, hold the camera in its normal landscape orientation. This allows gravity to help the dust fall down onto the adhesive strip at the bottom of the sensor housing.
