Huawei Mate 20 Pro, LG V40, Galaxy A9: Multiple rear camera smartphones are mainstream

Each of these smartphones have different setups, each suited to serve different purposes.

Launched back in March, the Huawei P20 Pro was the first smartphone to feature a triple-camera setup. Since then, we have seen many brands try their hand at launching smartphones with multiple rear camera setups. In fact, Samsung seems to have launched two in the last couple of weeks itself. There are only a handful of smartphones so far which offer the novelty of switching between lenses, but they all do it differently, which automatically results in visually different images.

Each of these smartphones has different setups, each suited to serve different purposes. It also caters to a different group of buyers, because of the price the smartphones are being offered at.

So here's a guide for you, detailing some of the multiple rear-camera setup sporting smartphones we have seen the launch in the last few months. By multiple rear-camera setup, I mean smartphones having more than two rear cameras. I will also try decoding which phone is better suited for which type of photography, given the choice of lenses.

Huawei Mate 20 Pro

On paper, the just-launched Huawei Mate 20 Pro features a camera setup which is identical to the P20 Pro when it comes to “megapixelage”. The Mate 20 Pro features a 20 MP camera for super wide shots, one 40 MP shooter in a conventional wide-angle and one 8 MP telephoto camera. What has changed though, is that Huawei ditches the monochrome sensor for larger regular sensors compared to the P20 Pro.

The primary 40 MP sensor features an aperture of f/1.8, while the ultra-wide lens has an aperture of f/2.2. The telephoto lens is capable of 3x optical zoom and a 5x hybrid zoom. The telephoto lens also gets OIS which should help you use it better in low-light.

Huawei also claims to have improved its Master AI 2.0 image processing which is now capable of segmenting elements in an image. This should result in better processing but there’s very little we can say without actually seeing that for ourselves.

Samsung Galaxy A7

Samsung's highlight for one of their newest additions to their mid-premium A Series — the Galaxy A7 — range is that it sports three cameras at the rear. This comprises an 8 MP shooter with an ultra-wide 120-degree lens, a 24 MP primary camera and a 5 MP "depth" camera.

The primary 24 MP sensor which does the work of capturing light, features a f/1.7 aperture which allows it to capture more light in low-lit scenarios. The 8 MP ultra-wide camera meanwhile features an aperture of f/2.4 which means that taking shots in poorly lit areas will be a struggle. The depth sensor meanwhile features an aperture of f/2.2.

The cameras here also use Samsung's Intelligent Scene Optimiser, which figures out what you're shooting and adjusts the contrast, brightness and colour to optimise image quality.

The Samsung Galaxy A7 is selling in India from Rs 23,990 onwards.

Samsung Galaxy A9 (2018)

Samsung announced the 2018 edition of the Galaxy A9 recently with four rear-facing cameras, the first phone in the world to have one. While four camera can be better as they offer versatility, the fourth camera on the A9, similar to the A7, is only a depth sensor.

The topmost lens in the module is a 120-degrees ultra-wide lens with an 8 MP sensor and an f/2.4 aperture. This lens is said to make capturing panoramic shots easier for users. Samsung says that this lens captures whole scenes with less panning. There's also a telephoto lens here which was missing on the A7. This is a 10 MP sensor with an f/2.4 aperture, offering 2x optical zoom. This lets you capture more detailed images even when you are farther away from their subject.

The Galaxy A9’s third camera (from the top) is the main snapper. It features a 24 MP sensor and aperture of f/1.7, identical to the one on the A7 (at least on paper). Samsung mentions in a blog post that the lens here uses an algorithm (fancily named "pixel re-mosaic") that is capable of maintaining peak performance even in low light conditions, which should effectively reduce noise in images.

The fourth camera is a 5 MP depth sensor with an f/2.2 aperture.

LG V40 ThinQ

LG was one of the first smartphone makers to feature a dual-camera setup on a phone when they launched the Optimus 3D back in 2011. Fast forward to 2018 and the Korean manufacturer recently announced its final flagship for the year with three cameras on the back.

To talk numbers, the primary camera is a 12 MP unit with an aperture of f/1.5 and a 1.4-micron pixel size. Apart from the larger pixel size and a lower aperture, the lens also features three-axis OIS as well as dual-pixel autofocus. In theory, this should let you take great low-light shots without breaking much of a sweat.

As for the other two lenses, one is a 12 MP telephoto lens with an f/2.4 aperture with phase-detection autofocus as well as OIS. The wide-angle lens is a 16 MP unit with an aperture of f/1.9. In fact, the wide-angle module has been borrowed directly from the LG G7 ThinQ we recently reviewed.

Unlike the Galaxy smartphones, you get a choice of three lenses, each offering you a completely different output of what you intend to shoot.

Huawei P20 Pro

Huawei might not have been the first smartphone brand to slap two cameras onto the back of a smartphone, but they definitely were the first to feature three. While it does sound like a game of numbers, the P20 Pro is by far the best implementation I've seen. That statement does come with a few caveats though and that's because I'm yet to get my hands on most of the phones in this list. This includes the LG V40 ThinQ, the Samsung Galaxy A9 (2018) and the just-announced Huawei Mate 20 Pro.

On the P20 Pro, you get a 20 MP monochrome camera, a 40 MP RGB camera and an 8 MP camera which provides the 3x optical zoom support. Now, while the 40 MP sensor comes with a f/1.8 aperture and the 20 MP monochrome sensor comes with a f/1.6 aperture, the telephoto lens in front of the 8 MP camera comes with a f/2.4 aperture. While that in itself sounds quite nice when seen on a poster or an advert, what do they each do?

The 40 MP sensor is the primary camera and captures the colours. Huawei employs pixel-binning which gives you a 10 MP image, which lets you zoom up to 3x optical and 5x digital. You can also select the 40 MP format, but that will not allow you the zoom feature. The 20 MP monochrome camera simultaneously captures detail, assisting the primary camera in improving sharpness. The 8 MP camera meanwhile provides the optical zoom and additional focal length, therefore functioning as a separate lens unit.

Here is the Huawei P20 Pro photo album on Flickr, which will give you a good idea of how the P20 Pro camera performs.

We will be adding on to this list as and when more multiple rear camera setup smartphones launch in the market. So do keep checking back for this one-stop destination for all things with multi-camera smartphones.
