Odd bokeh was one of the risks of adding a mechanical aperture, and bokeh is very often weirdest at the first or second down from open.
I would hope that the telephoto lens does not show this so severely (because it has a fixed round aperture) but all mobile phone lenses in my experience have had a tendency towards a sort of concentric-ringed, quasi-soap-bubble bokeh; it's a common part of the challenge of really tiny optics (that you either like or dislike). (The iPhone X was really distinctive in this regard). So it's not too surprising to see the aperture do this on top of that.
As a general rule you don't see it in average images, but I guess sensors are now high-enough resolution that it's becoming more obvious, and the blades of a mechanical aperture might make it quite noticeable in some situations.

Why? Where can I read/learn more about this?

I haven't seen a diagram of how the aperture in this new iPhone is designed yet. There's a lot of different ways to do it, with lots of odd shape possibilities.
dofm 10 hours ago
Also because of things like angle of incidence?
The purely round lens will generally have nice round (or at least cats-eye) bokeh across the frame with an edge that degrades softly as a result of aberration, so beams of light from different angles tend to blur into each other.
As soon as you get aperture blades, you lose that soft edge, get contrast but also a lot of competing shape influences at different angles. They will tend towards more rounded shapes as you stop down more.
And that is putting aside that some aperture shapes are just really insane when they are nearly wide open, right? (Konica 40mm f/1.8 AR I am looking at you with your shuriken bokeh)

Six blades with a slightly rounded hook in them by the look of it. Very noticeable sun stars at f/1.8, nice looking results at f/2.8.
Absolutely insane mechanical challenge and assembly challenge.

Edit: just saw your update with the photos of the mechanism. Wow that's impressive miniaturisation. The hexagonal shape looks surprisingly good. I wonder what's causing the odd effects in the OP. I have noticed in the past that iPhone cameras produce square specular highlights through tree foliage, so I wonder if it's an extension of that oddity.
dofm 10 hours ago
I found myself looking at it when I was considering making a DIY aperture for my DIY lenses. (I've personally settled on swappable Waterhouse stops for now but I might fit an eBay microscope aperture, many of them have loads of blades).
Oh and now I'm going to end up looking on eBay for a Minox 35ML or 35GT again. Seriously, never do this while logged in; Minox 35 sellers may be among the most desperate I've ever seen in terms of sending you offers, it's relentless.
robotmay 10 hours ago
Coincidentally I think I have a non-working 35GT in my market stall (https://camerasetc.wales), so if you want a project drop me an email as I'll send it to you for the cost of postage. I have too much in my repair backlog and those things are fiddly little bastards at the best of times :D
dofm 10 hours ago
I too have too much clutter so I will have to turn down your kind offer but I will peruse your sites and I may ping you a note sometime about a particular lens I have been looking for — quite a random cheap old one I regret parting company with. (I'm in Kent but I have a friend in Cardiff and if my wallet does not protest I may pop in on your stall)
robotmay 9 hours ago
That reminds me that I need to do a new update post, whoops. I've had an absolute buttload of Pentax K mount gear the past couple of months, which is quite annoying as I don't have that many customers that shoot it. I'll have to big up the Pentax cameras a bit more haha.
Do swing by if you're ever in town when the market's open! I've always got lots of fun cheap stuff kicking about, and a bin of broken shit if you need parts :D

Because they are a nightmare to own. So lovely when they work but so frustrating because you keep readjusting the shutter mechanism with those tiny screws and you end up wasting so many rolls (and pictures) in the process.
I own a 35GT, barely use it but wouldn't sell it because I have too much empathy. It would feel like receiving money to spell a malediction on someone.

Heavily ringed bokeh just comes from the optics.
dofm 10 hours ago
Errr, quite obviously not, indeed. But then I didn't say they were?
I said all phone lenses tend to have soap bubble bokeh as a consequence of their optics. Almost all phone lenses don't have mechanical apertures; they have fixed ring apertures and also tiny aspheric lenses.
(In the industry it's seemingly called "onion ring bokeh" to distinguish from soap bubble, presumably because it has more than one ring.)
However! The first stop down of a mechanical iris has a tendency to have odd effects on the lens's bokeh.
You get an interference of the aperture blades and the wide-open bokeh. With a lens that is prone to ring bokeh, slightly stopping down will smear the edge of the bubble, but in this case it is also clearly boosting contrast as you expect (and an irregular shape at different angles)

Even on the 18 Pro Max the 8x zoom of the telephoto lens is just the 4x using the same 12 MP crop of the 48 MP sensor to "double" the 4x optical zoom as the last generation. I hope we can get some level of optical zoom on a future Duo.

Previously the blur on iPhone was all software, apparently. I've set mine to do wide open with no bokeh, and i'll put it in after.
But to be honest, the iPhone is the camera I have on me, so the limits are acceptable. Can I force focus it? No. Can I get the glow? No. But iPhone + zoom + crop is better in some ways than my 50mm 1.2 with bokeh.
ValentineC 5 hours ago
I mean, consumers would probably just know it as "nice and pleasing blurred background", versus "this blurred background isn't as nice".

The average user may not understand the technical details of bokeh but they will certainly have an opinion on what is pleasing to the eye.
josephg 4 hours ago
Well, yeah. f1.2 is a nice gimmick but opening up so wide rarely translates into better photos. Don't get me wrong - you can get some beautiful portraits with that lens. But in practice, my 24-70 f2.8 zoom lens gets way more use than a 50mm prime.
There's a reason high end phones have multiple cameras on them. It's because not every photo wants to be taken at the same focal length.
I'd much rather a mirrorless camera with a 24-70 than an iphone. A mirrorless camera with just a 50mm prime will take some beautiful photos. And some photos you won't be able to capture at all.

PetaPixel reviewed the bokeh, and called it "meh" and "not very nice". [1]
A lot of the iPhone reviews are very rushed in order to have a review ready by the time the embargo is lifted. I think the PetaPixel review is quite thorough given the limited amount of time they had to actually use it.

Where are the measurements? All I see are vague generalities like "well-rendered images with improved contrast and natural-looking skin tones". I guess those are the "perceptual analyses"? Is there a "See full measurements" button I'm missing? How do they come up with numbers like "157 Portrait", "172 Outdoors"?

For instance th Xiaomi Ultra 17's main camera is faulted for having shallow depth of field or "autofocus decision errors", which I assume just means the auto selected subject wasn't the person straight in front of the camera ? [0]
These tests seem to be about versatility and predictability more than sheer performance.

Samsung in the past has also held that distinction, being able to take very good still pictures, but they too fell down when it came to hardware and software, particularly when you start adding in video performance, which requires better software/hardware chops. Nothing is gonna beat Apple chip hardware right now.

Computational photography isn't just the smoke-and-mirrors of AI upscaling faking information. You really can get around the limitations of physics on a traditional lens with non-generative computational photography techniques, incorporating real information, like the time-series data over the length of an exposure, the data from other sensors like the accelerometer or lidar, or data from an array of lenses (as others have pointed out).
Even without those tricks, the Pura 80 Ultra specifically uses a much larger camera sensor than most phones.

As someone who has only been an Apple user for phones (and Canon, Sony and Leica elsewhere), AI or otherwise, Apple is not immune to relatively heavy post processing in software. They're certainly not inserting moons, but even the raw sensor data has had some uplift to it.

And I fear the more tech reviewers do these pixel peeping side by side comparisons between phones, the greater the incentive to cheat.

I use GrapheneOS for my own phone and have always been forced into iPhones at work.
iOS, after 12 years of use, is still so terrible that I can't just get over it.
I open my MacBook and will do whatever needs to be done from there.
I should probably get an iPhone for private use too though. It would surely stop me from being on my phone more than I'd like to.

Mockery aside: it's all the same. They're all good enough for portraits where all you want is some depth of field & contrast, they're all good enough for landscapes where they capture colors pretty well, and they're all catastrophic past 5x zoom. You can take the top 10 of DXOMark (hell, the top 20) and you won't realistically find a difference unless you're pixel peeping. Which, we all know your phone pictures are just being sent compressed over Whatsapp, it doesn't matter. If you want camera quality pictures, get a camera. Even a 15 year old shitty Canon will take better pictures than the 18 Pro.

This is like saying most users will never adjust the shutter speed. Of course they won't, because the software automatically adjusts it, just like it does on any traditional camera. For the aperture capable lens, the software adjusts the aperture automatically depending upon light and/or depth of field requirements of a scene.
And yes, photographs are still spectacularly important.
But...I don't get it regardless. You know that video also uses apertures on every such equipped device, right? Better depth of field if the environment allows it is a good thing.
> Apple appears to only care about still pictures up to a certain point
I feel like people are just saying silly bullshit now. Apple has made video a core part of their product reveals for years now. And current iPhones take outrageously good videos.

I mean, one of the uses is the statement "Its variable aperture is a particular strength, significantly improving the camera’s ability to maintain sharpness in complex scenes and when multiple subjects are present.".
DXOMark is a technical test with generally little narrative, so I'm not sure what your point even is. Would it surprise you that their reviews of SLR lenses, where the aperture is a critical element of the lens (and it would be a joke not to have one), they generally don't mention it at all?

Presumably because others disagree. I also do not see it here. Zooming in there are clear pores and skin texture. Is it somewhat smoothed? Yeah, it has that feel. Does it look like a cheap rubber mask? No. And that phrasing is frankly very insulting to the pictured subjects.

This is a heavy walk-back from reptile wearing a rubber mask. It should not be hard to understand why that statement can be seen as insulting.

Not really. It’s a bit smoothed but the smoothest parts of her face are also where the skin is stretched tightest from smiling. It is actually smoother in those areas. I don’t see a ton of difference in the foreground between the skin texture in the different photos.
Background is different but as you said, that’s blood from a stone. The data just isn’t there.

It's very hard to understand. It doesn't make sense that a criticism of the camera would be an insult to the subjects of the photo.
The criticism is that the image isn't an accurate representation of the subjects. If B is bad, and B != A, it doesn't follow that A is bad.
