Summary
Nikon has released firmware 1.10 for the NIKKOR Z 24-70mm f/2.8 S II, improving aperture-operation reliability and reducing aperture noise.
Released on October 22, 2026, the update takes the lens from firmware version 1.00 to 1.10. Both changes concern the aperture mechanism; Nikon does not announce new features or optical-performance changes.
What changes with the aperture
First, Nikon lists improved reliability of aperture operation. Second, the firmware reduces operating noise from the aperture. Nikon provides neither numerical measurements for the noise reduction nor details of the circumstances behind the reliability improvement.
The NIKKOR Z 24-70mm f/2.8 S II is a professional full-frame zoom with a constant f/2.8 maximum aperture and an internal zoom design. For video creators adjusting aperture while recording, quieter operation can be useful, especially with a microphone mounted close to the camera. Nikon does not claim that aperture noise has been eliminated completely.
How to install the update
The lens firmware is updated with the lens attached to a compatible Nikon camera. You also need the camera’s memory card and a compatible card reader. Nikon advises that the lens may move during the firmware update.
Before proceeding, check the current lens firmware version, the compatible-camera list and Nikon’s installation instructions. If version 1.10 is already installed, there is no need to install it again. Downloads for Windows and macOS are available from Nikon’s official page.

What we think
This is a modest update, but it addresses something that can be genuinely annoying on a video shoot: the mechanical sound of the aperture when exposure changes. In a quiet scene, particularly with an on-camera microphone, that sort of detail matters.
We like seeing Nikon refine how a lens behaves rather than focusing only on headline features. There are no before-and-after recordings or measurements here, though, so we cannot say how noticeable the improvement will be in every setup. If you own this specific lens, it is worth scheduling the update ahead of your next assignment and leaving time for a quick operational check.
Frequently asked questions
Which lens is firmware 1.10 for?
It is specifically for the NIKKOR Z 24-70mm f/2.8 S II, not the earlier NIKKOR Z 24-70mm f/2.8 S.
Do I need to install it if my lens already has firmware 1.10?
No. Nikon states that installation is unnecessary when firmware 1.10 is already installed.
