And here's the same photo taken with the iPhone XS. There's little difference between the two in terms of quality.
Both phones have a dedicated 2x zoomed lens. Here's the Galaxy S10's 2x zoomed lens in action, which is slightly sharper than the iPhone XS's 2x zoomed photo.
And here's the iPhone XS's 2x zoomed lens, which isn't quite as sharp as the Galaxy S10's, but it's nothing to complain about.
And here's the iPhone XS's 10x zoom.
Compared to the iPhone XS's photo, the Galaxy S10's photo is brighter. That can be good for capturing as much detail as possible, but it does result in a flatter photo than the iPhone XS's darker photo, which has more depth and contrast to it.
The majority of photos I took with the Galaxy S10 and iPhone XS looked very similar. Here's the S10 again.
It should be noted that the Galaxy S10 tends to oversaturate the color blue at times. I found the same when comparing the cameras on the Galaxy S10 with the Pixel 3's.
But the real difference between the Galaxy S10 and iPhone XS becomes obvious with the S10's ultrawide camera.
Here's another example, starting with a photo from the iPhone XS.
As a sidenote, there's a strange dark shadow around the Freedom Tower in NYC.
Both the iPhone XS and Galaxy S10 take similar quality photos, and it's pretty clear that the Galaxy S10 differentiates itself from Apple's latest iPhones with its ultrawide camera.
Admittedly, I wasn't a fan of ultrawide cameras when I first saw them on LG's G5 smartphone from 2016. It was only when the LG V40 came out in 2018 that I started to appreciate ultrawide photos.
Now, it's pretty clear that ultrawide cameras aren't a gimmick. They help you capture a lot more of your surrounding, especially of nearby larger objects.
It's also pretty clear that Apple should add an ultrawide camera to its next iPhone if it wants to compete against Samsung and LG in the camera department.
