The iPhone Duo Ultra Wide camera comes with a 48MP sensor, 13mm focal length, f/2.2 aperture and a 120-degree field of view. Apple says it matches the Ultra Wide camera on the iPhone 18 Pro, while also supporting 48MP macro photography. That makes it the only rear camera on the Duo designed for both the widest 0.5x shots and close-up photography.

iPhone Duo Ultra Wide Gets 48MP Camera Like 18 Pro

The iPhone Duo Ultra Wide camera is one of the phone’s most notable rear-camera features, with Apple listing a 48MP sensor, 13mm focal length, f/2.2 aperture and 120-degree field of view. Apple also lists 48MP macro support, making the Ultra Wide the camera responsible for both the widest shots and close-up photography on the foldable iPhone Duo.

iPhone Duo Ultra Wide camera specifications

The iPhone Duo has two rear cameras, and the Ultra Wide is the second lens in the system. According to Apple’s published specifications, it uses a 48MP sensor with a 13mm focal length and an f/2.2 aperture. Its field of view is 120 degrees.

The camera also supports 48MP macro photography. This gives the Ultra Wide a dual role in the camera system: it handles the 0.5x wide-angle view while also being used for close-up photography.

iPhone Duo Ultra Wide matches the iPhone 18 Pro

Apple says the iPhone Duo Ultra Wide matches the Ultra Wide camera on the iPhone 18 Pro. The specifications published for both phones list the same 48MP resolution, 13mm focal length, f/2.2 aperture and 120-degree field of view.

That makes the Ultra Wide the rear camera specification where the Duo matches the iPhone 18 Pro despite the difference between the two camera systems. The iPhone Duo is listed at $1,999, while the iPhone 18 Pro is listed at $1,199 in the source material.

What the iPhone Duo camera system gives up

The matching Ultra Wide specification does not mean the entire iPhone Duo camera system is equivalent to the Pro models. The Duo has a 48MP main camera with a fixed f/1.6 aperture, while the iPhone 18 Pro has a main camera with four aperture stops ranging from f/1.48 to f/4.0.

The bigger difference is the lack of a dedicated telephoto camera on the Duo. The iPhone 18 Pro has a 48MP tetraprism telephoto lens at 100mm with an f/2.8 aperture. The Duo does not have a telephoto lens.

As a result, the Duo’s framing options from 0.5x through higher zoom levels rely on its Ultra Wide and main cameras. The published optical steps for the Duo are 0.5x, 1x and 2x, compared with 0.5x, 1x, 2x, 4x and 8x on the iPhone 18 Pro.

48MP macro photography on the Ultra Wide

Apple lists 48MP macro support with the Ultra Wide rather than the main camera. This follows the common arrangement in which the widest camera handles close-up photography.

For the iPhone Duo, this means the same rear camera covers both ends of the phone’s useful camera range. The Ultra Wide provides the 0.5x perspective for wider scenes and is also used for macro shots, while the main camera handles the central part of the system.

Apple has not published a minimum focus distance for the Duo’s macro photography. The company also has not stated in the supplied specifications whether macro switching is automatic.

120-degree field of view explained

The 120-degree field-of-view figure describes how much of a scene the Ultra Wide lens can capture. It is not a measurement of image quality.

Apple lists the same 120-degree figure for the Ultra Wide camera on the iPhone 18 Pro and iPhone 18 Pro Max. The wide field of view is particularly relevant on the Duo because the phone has a large 7.6-inch inner display that can act as a viewfinder when the device is open.

Camera features and video support

Apple lists several photography and video features for the Duo’s camera system without specifying which individual lens supports each feature. These include Deep Fusion, Smart HDR 5, Night mode, Portrait Lighting with six effects, Photographic Styles 3 and Smart Focus tracking.

The published video specifications include 4K Dolby Vision recording at up to 120 frames per second, Cinematic mode up to 4K at 60 frames per second, Action mode up to 2.8K at 60 frames per second and Dual Capture at 4K 30 frames per second.

The camera system also includes a sapphire crystal lens cover and True Tone flash. Both the inner and cover displays can serve as viewfinders, while the phone has a Camera Control button with a Siri Camera mode.

What Apple has not confirmed about the Ultra Wide

Apple has not listed stabilization for the iPhone Duo Ultra Wide. Sensor-shift optical image stabilization is listed for the main camera, but the supplied specifications do not provide the same information for the Ultra Wide.

Apple also has not published the Ultra Wide sensor size, pixel size or minimum macro focus distance. The company has not specified whether the 48MP Ultra Wide can record video at its full resolution or which individual frame rates are supported by that lens.

These missing specifications mean the camera’s real-world performance cannot be determined from the published specifications alone. The supplied source also states that no one outside Apple has used the camera, so claims about its actual image quality or low-light performance would be premature.

iPhone Duo pre-orders and availability

According to the supplied information, iPhone Duo pre-orders open on Friday, October 16 at 5 a.m. PT. Shipping is scheduled to begin on Friday, October 23.

The iPhone Duo’s Ultra Wide therefore stands out on paper for matching the published Ultra Wide specification of the iPhone 18 Pro while also providing 48MP macro photography. However, the Duo’s overall camera system remains different from the Pro models because it has two rear cameras and no dedicated telephoto lens.
