Every hardware have it's limitations, my DSLR don't fit in my pocket for instance. But that wouldn't be a fair point when comparing photo quality against a smartphone.

Comparing quality with non equivalent focal lengths is as pertinent as to mount a fisheye on the DSLR (because you can!) and then claim that the smartphone have less distortion.

I was about to disagree with you - but I think you're right. The photographer clearly took a couple steps back when they took the DSLR photo. You can tell by looking at the trees in the background - they appear much bigger in the DSLR photo because they're using a longer focal length.

I think a DSLR would struggle with the same perspective distortion if you put an ultrawide lens on it. It would have been a much more fair comparison if they took both photos from the same spot and zoomed in with the iphone.

I'd agree if the phone had an appropriate focal length, but it doesn't. You can either go way too wide, or way too narrow (with a worse image sensor at that). Comparing the best the phone can sensibly do while handicapping the camera by intentionally doing the wrong thing for the situation makes no sense.

The only workaround for the phone would be to still step back and take the image with the 24mm equivalent, then crop the image a whole lot to get an appropriate and equivalent view.

Note that "proper" lenses have more room for corrective elements in their lens stacks, so decent quality setups should experience less distortion than the tiny smartphone pancakes.

An ultrawide will never be good though, it's a compromise for making things fit or making a specific aesthetic.

How do you know if the phone doesn’t have an appropriate focal length if the image isn’t marked?

Secondly, none of the points in the article are about optical distortion across the lens they’re all about perspective distortion. Corrective elements aren’t going to change that. None of the examples highlight barrel/pincushion distortion or the like as an offender.

		> How do you know if the phone doesn’t have an appropriate focal length if the image isn’t marked? I listed focal lengths for an iPhone 16 Pro Max, and good focal lengths for flattering portrait photography is common photography knowledge that I provided as well for reference, set with a little wiggle-room by the optics of the human eye. There aren't more variables than subject framing and focal length, and a portrait of a person is a well-known size. Comparing the remaining two numbers is simple math. (It is well-known what distortion effect using the "wrong" focal length will give, which can sometimes be used intentionally but is not what you want in the average portrait. Shorter focal lengths give a silly, elongated facial appearance which exaggerates frontal features like nose and mouth, longer focal lengths give a flatter appearance which exaggerates rear features like neck width.) > Secondly, none of the points in the article The article clearly shows distorted images, and that the article fails to mention it does not make it less of an issue.

The article is comparing photo quality between two different cameras. The lens affects image quality, so it's completely fair to discuss.

If it were possible to switch out the lens on the iPhone, and the photographer had just chosen the wrong lens for the job, that would be a fair criticism of the article. But that's not what happened. The iPhone is just very limited when it comes to the lens, compared to a DSLR.

		> If it were possible to switch out the lens on the iPhone... It is possible to "switch out the lens" on an iphone, because iPhones ship with multiple camera lenses. (Well, multiple entire cameras). The iphone 16 they're using here has 3 cameras. And yet, I'm pretty sure the photo of the boys was taken with the ultrawide for some reason. A lot of the distortion problems would go away if they took a few steps back and used one of the longer lenses - just like they did with the DSLR.

		You can always crop a wide shot. Most of the criticism comes down to not standing in the same spot for both photos (I’m unconvinced that the difference in jawlines, for example, is not because the subjects moved while the photographer did). You can take a bad picture with any camera.
