The Huawei Mate 9 has one of the best cameras in the mobile phone industry due to its dual-camera setup. The relatively new iPhone 7 Plus, meanwhile, also is good. Let's see how the Apple iPhone 7 Plus fares against the Huawei Mate 9 in a duel of dual-cameras.

The primary shooter of the Huawei Mate 9 Pro is a second generation Leica dual-lens f/2.2 camera with a 12 MP RGB sensor and a 20 MP monochrome sensor. It has optical image stabilisation (OIS) and phase detection features. Although images produced by the Mate 9 in adequate light conditions are in-depth and detailed, the auto-HDR mode tends be overwhelming against direct sunlight.

Low-light shots taken with the Mate 9 aren't that impressive even with OIS. The Huawei flagship's dedicated monochrome sensor disregards the need for filters on black-and-white shots. The variable aperture mode is sufficient, but can sometimes obscure a large portion of the foreground. The Huawei Mate 9 and Huawei P9 front-facing 8 MP f/1.9 selfie camera is better than that of the iPhone 7 Plus. It comes with autofocus and sensor-activated shutter.

The main camera of the iPhone 7 Plus is a dual 12 MP shooter with a 28 mm f/1.8 aperture. It has phase detection autofocus, 2x optical zoom and quad-LED flash. The lens of the iPhone 7 Plus takes in considerably more light compared to that of its predecessor, the iPhone 6s Plus.

The iPhone 7 Plus camera also has OIS, which helps produce secure shots despite of shakes and bumps. The iPhone 7 Plus is capable of simultaneous 4K video and 8 MP image recording and has touch focus, face/smile detection and HDR features. The handset has a 7 MP secondary camera with 32 mm f/2.2 lens, capable enough to create 1080p HD videos at 30 FPS and 720p slow motion videos at 240 FPS.

While the latest Apple flagship resolves abundant details in decent lighting, it isn't categorically better than previous iPhone variants. Certain softness in corners of some shots can also be seen at times.
