iPhone X vs Sony A7R III camera showdown: There's an app for that

Smartphone photography has been improving with each generation of device, and it's not unusual these days to see theater releases shot on iPhone. All the same, there's still a little skepticism out there about just how well an iPhone sensor can hold up to a dedicated camera, and whether it's just a stopgap or could actually be the device you should reach for first.

That's the question director and videographer Tristan Pope set out to answer in his side-by-side video comparing the iPhone X and the Sony A7R III. The third-generation of Sony's interchangeable lens camera has no shortage of advocates, with its 42-megapixel sensor, speedy focus, and solid low-light performance. However, Pope argues, that's not to say the iPhone X isn't capable of keeping up.

In a fifteen minute video, he shows side-by-side shots from the Sony and from the iPhone, and the results might surprise you. With a few accessories – like some LED lighting – both camera and smartphone are undoubtedly able to deliver impressive portraits.

While the idea of a smartphone being capable of competing with a dedicated, high-end camera is impressive, arguably a comparison alone is fairly limited in its use. After all, if you've got a Sony A7R III then you're probably going to use it – if you haven't, but you do have an iPhone X, you'll use that instead. What's more useful is the app workflow Pope shows.

One of his go-to apps, it turns out, is Focos. It takes advantage of the dual cameras on the iPhone X – and other iPhones – and the fact that Apple grants access to the depth map data, to allow for some serious tweaking and modification of things like bokeh. That includes even the size or shape of the bokeh, whereabouts it starts in the frame, and more. "All the equivalent low f stop lenses by themselves would cost a fortune," Pope points out.

The big question – and it's not a new one, of course – is which is better. As you might have predicted, the answer to that isn't straightforward. "All of the different apps that you can do so many tweaks to your photo, right there, and have it ready to go – on your phone – to send off to social media, the iPhone is an invaluable tool to have," Pope concludes. All the same, that's not to say the Sony wouldn't earn its place in your bag.

"That being said, shooting with the Sony A7R III is not replicable," Pope says. "The quality of the images, the megapixels and the punch and the smoothness and quickness ... there' s a lot of things that make it so that these two together make an awesome, awesome team."

With a street price of around $3,200 for the Sony, and $1k for the cheapest iPhone X, neither is exactly a cheap way to take portrait shots. If you want to try out Focos, mind, it'll run on the iPhone 7 Plus as well as Apple's 2017 models (though not the iPhone 6 Plus) which you can pick up new from $669. It might not replace a full interchangeable lens camera or DSLR, but as this video shows, get the apps right and you might not miss the difference too much.
