I think the iPhone 11 makes some good advances as outlined in the linked article, but a lot of the pictures didn't particularly wow me at all from a camera capabilities perspective. A bunch of the images at the top of the article are nice, but that is entirely due to the photographer's skill at composing aesthetically pleasing shots and have little to do with the actual capabilities of the iPhone 11.
As someone who owned the LG G3 years ago, and absolutely loved the wide-angle lens on that phone, most of these pictures would look identical. I guess the point I am making is that while it's exciting to have a wide-angle lens on the iPhone 11, it doesn't in any way move the bar compared to what's been out there for a while.
Where the iPhone 11 has improved drastically, is with night mode shots, and that's somewhere it has been lacking substantially compared to the competition. They've done a really good job catching up and maybe even surpassing the competition in some areas. Kudos to them for that.
That being said, you aren't going to get great prints out of night mode images for anything much larger than post-card sized prints with the iPhone 11 (or any other smart phone camera to be honest). I love the image of the person in the boat at dusk, but even at the size displayed, you can see a bunch of artifacts from noise reduction. As much as everyone loves to hate on DSLRs these days, you are going to get much cleaner images in these light starved environments with a large sensor and good lens. I personally think it's absurd to make that comparison, but I just had to say this because every article about the latest smartphone camera ends up having a bunch of comments about how they are superior to DSLRs at this point (which they are on the computational photography side of things, but good luck getting clean, large prints out of a phone camera, especially in low-light situations)
