Buyers Guide

If you’ve been a photographer in the last 20 years you can probably remember the megapixel wars between the major camera manufacturers in the first decade of the 2000s. As we push into the 2020s the megapixel race has reignited not with the once-mighty DSLR but with everyone’s new camera of choice, the smartphone. So which smartphone camera has the most megapixels?

It’s a rather complex question. With traditional interchangeable lens cameras we’ve come to realise that more megapixels doesn’t necessarily mean better image quality. Every sensor is divided into however-many-million-pixels, each of which gathers light independently.

That means pixel size also plays a role as the larger the photosites, the more data they can record. It’s a question of balance, but generally speaking, a larger sensor with fewer, bigger pixels will produce better quality images with greater dynamic range.

So how do smartphone cameras like the Samsung Galaxy S20 Ultra, which boasts 108 megapixels, produce such sharp images? Well, technology has evolved and smaller pixels have more light-gathering ability.

As mobile phone processors and software have advanced, there are digital tricks to improve image quality. In short, smartphone sensors are now able to combine data from multiple pixels in order to create a ‘final image’ that theoretically increases image quality.

Some smartphone cameras, such as the Samsung Galaxy S20 Ultra for instance, combine data from 9 megapixels into one for more detailed images.

In other words, when it comes to smartphone cameras, the hardware is no longer the most important component. The evolution of AI and computational photography software has enabled smartphone camera sensors to exceed the limitations of their physical size.

So with smartphone cameras it’s interesting: it’s all about the megapixels… but it also isn’t. The more megapixels on your interchangeable lens camera, it really depends on the size of the pixels. But with smartphone cameras it’s largely down to the software.

Smartphone cameras with the most megapixels also tend to incorporate software that combines data from multiple pixels. And where this really shines is in these cameras’ night modes. Typically, they are able to harvest the best bits from the frames of a short burst of video that recreate the effects of stabilisation.

So when you’re looking for the smartphone camera with the most megapixels, rest assured that this isn’t a reboot of the halcyon days of the 2000s megapixel wars. A 108MP smartphone sensor is indeed much more powerful than those other 48-megapixel offerings.

Samsung Galaxy S20 Ultra

  • Video Resolution: 8K at 30fps, 4K at 120fps
  • Zoom: 100x Space Zoom
  • Audio: Zoom-in mic

The Galaxy S20 Ultra is not short on features, beginning with its camera. The quad camera array on the rear of the S20 Ultra comprises a 12-megapixel ultra-wide camera, 108-megapixel wide-angle camera, 48-megapixel telephoto camera and a depth vision camera.

What’s more, the S20 Ultra’s pixels capture more light thanks to nona-binning technology. This effectively combines nine pixels into one creating larger photosites that capture more light.

On the front of the Ultra is a 40-megapixel selfie camera. Photo mode now offers what is called Single Take. In this mode, when you press the shutter the S20 Ultra records a short clip of video, and then AI selects your best frames.

Quick Take sees the Galaxy S20 Ultra employ all of its cameras at the same time. It then provides you with a selection of your best shots at different focal lengths.

The Galaxy S20 Ultra also adds 8K video recording at 30fps from the 108MP camera, as well as 4K at 120fps, Full HD and HD. 8K videos can be cast on Samsung’s 8K-ready TVs, or you can upload footage directly to YouTube.

Galaxy S20 Ultra users can also now film in Pro Mode. This means you have all of the same controls that you would were you filming with a DSLR.

Another interesting feature that proved very clever in my initial tests was the zoom-in mic. The Galaxy S20 Ultra’s microphone will effectively zoom in 6x to seek audio, and then follow that sound. This might be useful, for instance, if you were filming a live band or a speech at a wedding, and wanted to eliminate the background noise around you.

Space Zoom is the other big feature Samsung has introduced to its Galaxy S20 family. This is a new combination of hybrid optical zoom and AI-powered digital zoom. With the S20 Ultra you get 100x Space Zoom (the S20+ and S20 each extend 30x).

Like the P30 Pro, the Huawei P40 Pro has a four-camera system and again its produced in collaboration with Leica, the esteemed German camera manufacturer. For the P40 Pro Huawei and Leica have created a Vario-Summilux-H 1:1.8-3.4/18-125 ASPH camera system. That means that there’s an effective focal length range of 18-125mm and a maximum aperture of f/1.8 at the widest point and f/3.4 at the telephoto point.

The Huawei P30 Pro’s camera has a wider zoom range that runs from the equivalent of 16mm to 125mm. However, the P40 Pro’s main camera has a bigger sensor, which should be good news for image quality.

As in the P30 Pro, Huawei has used a periscope design for the telephoto lens in the P40 Pro. That helps to keep the phone’s thickness down while giving extra focal length.

Huawei has stuck with the innovative RYYB (red, yellow, yellow, blue) sensor design instead of the more common RGGB (red, green, green, blue) filter array. However, it has used this technology in two of the cameras in the P40 Pro, the 50Mp Ultra Vision Camera (Wide Angle, f/1.9 aperture, OIS) and the 12Mp SuperSensing Telephoto camera (f/3.4).

We’ll be honest here. The Huawei P40 Pro has a great smartphone camera that delivers impressively high-quality images in conditions that other cameras would struggle.

However, the current situation between Google and Huawei means that you can’t use many of the apps you’d take for granted on other phones. So while the camera scores very well, overall, the phone doesn’t deliver what many people want, which is a real shame.
