Final Cut Camera 2.4 Brings Manual Aperture to iPhone 18 Pro
Apple released Final Cut Camera 2.4 on September 29, 2026 as a free update with support for variable aperture on iPhone 18 Pro. Apple
The change centers on the Fusion Main camera. Apple says this is the first time iPhone users can set aperture directly, in this case from f/1.48 to f/4 inside Final Cut Camera. Aperture is the opening that controls how much light enters and how much of the shot stays sharp. 9to5Mac
For video, the control appears as shutter priority and aperture priority modes. One holds motion rendering steady while exposure is allowed to shift. The other holds depth of field behavior steady while the camera adjusts shutter. Still photographers and cinema operators will recognize the logic. Here it runs on a phone pipeline that also records ProRes and Apple Log, formats that preserve more picture information for editing.
The app was redesigned to fit the new settings. ISO for sensor sensitivity, white balance for color tone, and shutter angle for motion blur are now closer to the main screen. A two-finger tap hides the controls for a clear viewfinder view. Overlays can be customized with false color and clipping warnings for exposure, focus peaking with sensitivity control to show what is sharp, and a tally light to show recording is underway.
An iPhone can also be run remotely. Settings including aperture can be changed from a nearby iPad or Mac through Final Cut Pro. That allows the phone to work as a controlled second camera or crash camera without being touched during a take.
The edit side changes too. Final Cut Camera brings Cinematic mode tools to regular video, including ProRes and Apple Log, so focus points and depth of field can be adjusted later in Final Cut Pro. Final Cut Pro and Motion can now edit depth of field and focus points for video shot on iPhone 18 Pro. Depth data is no longer limited to Cinematic mode clips.
With iOS 27, Apple adds tools for monitored and live work. Final Cut Camera gains RGB Parade and histogram scopes, graphs that show color balance and exposure on an external monitor. It gains clean SDI out, which sends clean video through an HDMI-to-SDI converter for broadcast-quality streaming. It gains genlock offset, which corrects for artifacts from a filmed screen or timing gaps with other genlocked cameras. All three help with multi-camera sync and external monitoring rather than handheld shooting alone.
The new camera settings need an iPhone 18 Pro. Older iPhones receive the app update without the aperture control, priority modes, or depth-editing pipeline tied to the new optics.
Alongside the camera release, Apple updated Pages, Keynote, Numbers, Freeform and Pixelmator Pro for Creator Studio subscribers. Engadget Subscribers get new templates and themes in Pages, Keynote, Numbers and Pixelmator Pro. Keynote can automatically generate images to match slide content. Pixelmator Pro on iPad gains Select and Mask tools brought over from the Mac version.
Some changes apply outside the subscription. Pages, Numbers, Keynote and Freeform now allow users to request access to view or edit a shared file. Pages gains a Screen View option for reading and focused writing. Numbers gains new trigonometry, statistics and logic functions. Freeform boards follow the device dark mode setting and can be grouped into collections. Freeform supports Apple Intelligence Writing Tools for editing and generating text. The new Pixelmator Pro templates require the $13-per-month Creator Studio subscription.
In my view, the iris itself is less important than the control around it. Phone lenses remain small and limited by physics compared with larger cameras. What changes is precision and continuity from shoot to edit, with manual aperture, shutter angle, scopes, false color, peaking, remote control, SDI out and genlock working as one location kit. That narrows the practical gap between using a phone when it is convenient and placing it in a supervised production where exposure, focus and sync must repeat. For small crews and solo operators, that expanded range of jobs is the real gain, and it leaves the creative work where it has always lived, in front of the lens.
