It’s not an optical zoom, it’s just a feature that allows you to take pictures of things that are far away so that they appear closer. You know, like an optical zoom lens does.

"Telephoto lens" and "zoom lens" are not synonyms. There are plenty of ultrawide angle zoom lenses that would be completely useless for allowing you to take pictures of things that are far away.
 


In an interview with Numerama's Nicolas Lellouche, Apple's VP of camera software engineering Jon McCormack explained why the iPhone 15 Pro Max's tetraprism lens system is limited to 5x optical zoom, instead of 10x like on Samsung's Galaxy S23 Ultra. The interview is in French, so quotes below are computer translated.

Apple says the Telephoto lens on the iPhone 15 Pro Max features the company's most advanced camera stabilization system yet, with a combination of optical image stabilization and an autofocus 3D sensor-shift module. McCormack said the iPhone's 5x zoom lens can be stabilized "incredibly well" compared to a 10x lens.

"The 5x zoom is something that we can stabilize incredibly well," McCormack said in the interview. "If you look at the 10x zoom, unless you have the steadiest hands in the world or a tripod, it's really difficult to use."

Apple's senior director of iPhone product marketing Maxime Veron, who was also interviewed, added that the iPhone 15 Pro Max's 5x lens opens at ƒ/2.8, allowing for "excellent light management." By comparison, the Galaxy S23 Ultra's 10x lens has a ƒ/4.9 aperture. A lower aperture allows for more light to be captured by the camera's sensor, which can be especially beneficial for Night mode photos.

5x optical zoom is exclusive to the iPhone 15 Pro Max, with the iPhone 15 Pro remaining limited to 3x optical zoom. It has been rumored that Apple plans to expand the tetraprism lens system to both iPhone 16 Pro models next year.

McCormack and Veron discuss the latest camera innovations on all iPhone 15 models in more detail in the Numerama interview. The devices launch Friday.

IMO 5 x is just PR, which most people will swallow like a Candy 🤣
What Apple should be concentrating on is all lenses being 48 mega pixels an parity in quality between the lenses, it's just too big at the moment!
I would much prefer that, than all this oooh aaah on the telephoto lens 😡
 
As an 'enthusiast' photographer and I absolutely use my phone more and more. My dslr and mirrorless are better in some situations, but I'm routinely surprised how great of pictures I can get from my iPhone. I'm worried about taking great pictures regardless of the equipment I have with me at the time.

BTW, the statistics linked show some interesting things. One, there are almost as many iPhones sold in 2 quarters than there are stand alone cameras all year. Second, the average price of < $200 and the largest brand as 'other' tells me the volume is not from what people would consider pro-cameras.
Funny, I'm routinely amazed how poorly anything other than a basic landscape photo turns out from my iPhone.

Anything artistic, especially incorporating zoom and bokeh, requires a dedicated camera.
 
Very few actual photography "enthusiasts" have abandoned a dedicated camera for a smart phone. Point and shoot users are not enthusiasts.

Go to any dedicated photography forum, either online or in real life, and make that suggestion and be laughed out of the room. I realize we are on an Apple forum here so there is bias in pretending cellphones replace a dedicated full frame or crop frame camera, but you're way off base. Dedicated camera sales are growing, not shrinking. https://www.statista.com/statistics/1172711/forecast-of-digital-camera-sales-volume/

That is so wrong, on many fronts, and is nonsense.

I am one, as have many of my photographer friends, having been shooting exclusively with iPhones for almost 10 years. And coming from dSLRs, so-called "mirrorless cameras,", and even an Arca-Swiss F-field 4x5.

Great photography is about the photographer and his/her ability to see, not camera gear. I'd be glad to expand on that in much more detail.

Having experienced the S20 Ultra with its sub par camera and having since found my 3 yr old iPhone 12 Pro Max to be more than capable than any previous phone camera I’ve had.

I guess if there’s truth in 10x instability in the S23 and ease of use vs 5x in the IP15PM, then I’d assume that it’s reasonable for Apple to think that the older/less mobile/less tech geeky folks would be happy to take a hit on ultimate raw spec and gain some ease of use.

Also there’s gotta be some headroom there for future upgrades as technology (sadly) moves super slow for maximum revenue generation.
 
Again, tradeoffs… A 200mp sensor that fits in a smartphone will have tiny photoreceptors, which means reduced low light performance and dynamic range.
And it can merge pixels from 108mp to 12mp to increase light performance and dynamic range just like Apple did with 48mp to 24mp. Nothing new and simple to fix. Beside, who cares about the sensor quality with smartphones?
 
This is 100% of the issue.

The lenses on an iPhone aren't zoom lenses, they're fixed focal length and some of them are longer reach than others. So 'optical zoom' is a misnomer, you're just switching to a lens with a longer focal length to get a narrower field of view without cropping.

A 3x magnification lens cropped to 5x will generally produce a lower quality image than a 5x magnification lens, but a 3x magnification lens cropped to 4x will produce a higher quality image than a 2x lens cropped to 4x.

There's a trade off to be made between the 3x lens on the Pro and the 5x lens on the Pro Max (and an even bigger trade off if they had used 10x instead) and neither is objectively better than the other - the right tool depends on which kinds of photos you take most of. For me, I take far more photos in the 3x-5x range than I do in the 5x+ range, so the lens options on the Pro are more useful to me than the Pro Max. A 10x lens would be cool to have for the one time a year I might use it, but the vast majority of the time it's just going to take up space that could be used for something else.

Ideally Apple would be able to make the camera configurations independent of the screen size so you could choose a Max with a 3x lens or a non-Max with a 5x lens depending on which option makes more sense for your use case. But the folks arguing that 5x is objectively better for everyone and that Apple is doing us dirty by not using it on the smaller form factor are kinda missing the point.
Very well put 👏
Sadly most on here don't understand it.
 
Apple did the same with the iPhone 7 plus back in 2016 when portrait mode was exclusive to the 7 plus. It's all about marketing yada yada yada.

He's definitely right. I have trouble when I use the zoom on my S23 Ultra and even with the little pop up on the screen I lose sight of what I wanted and its hard to keep it in the shot.

You claim to have exclusively dropped dslr's and mirrorless cameras since 2013, so the iPhone 5s, IF you had the most recent phone, and also claim to be an enthusiast photographer.

*cough* bs *cough*

That's the problem with these forums, people post such bs all the time and claim to be what they aren't.
 
Samsung actually offer 3x and 10x so you can use it in different scenarios.
Ah, sorry, didn’t see that it had a fourth camera. I had checked a spec comparison sheet on Samsungs page, but they listed both telephotos on the same line. Yeah, with the fourth lens, it may be worth using a slightly higher telephoto range.

Hahaha, you sir are wrong.

I know at least a dozen people who have mostly gone to their iPhones to use it for photography or S23 Ultras or similar. I was one, who had a nice SLR camera, and didn't see the need to carry it with me any more. The ones I knew ran their own business and run it well with a smartphone now instead of their SLR cameras. They still use the lighting rigs if needed.
 
I get it, the further the optical zoom the harder it is to stabilize the shot. I think everyone knows that. But give us the option at least?

Actually maybe I'll take that back a bit. If it's 10x optical zoom and it's hard to get a stable shot, that means you won't be able to do 5x optical shots. 5x would basically be the main camera digitally zoomed until it gets to 10x. Maybe they could've added a 4th camera, but you don't want to add an extra camera for every level of optical zoom you want.
Also, as mentioned, you'd be likely crippling the aperture for everyone because in a phone format, it's pretty hard to build an f/2.8 lens for a 10X focal length (hence why Samsung's is f/4.9). It's about 1.5 stops difference, which means only approximately one third the amount of light gathered (each stop such as 2.8 -> 4.0 halves the light), so you'd be paying for it in all but perfect (ie. full daylight) lighting conditions. And 10X kind of takes you out of portrait range anyway so 5X is IMO a more usable focal length even if it is a compromise (isn't everything?).

You can certainly argue for 10X if you really need that reach and will always have a lot of light to work with. But I think 5X is a good compromise given current technology, for most people. The one thing that bugs me is specular highlights and lens flares from the 5X camera show a weird light pattern, very likely caused by how the light travels through the prisms. But it's not in every shot and not really a deal-breaker for me.

Based on the reviews I’ve seen, the iPhone 15 Pro camera outperforms the S23 in many settings.
What tends to happen in these reviews is they do a like for like comparison setting both phones at same x zoom setting. Yes the iPhone is better at that setting but when it goes past that x zoom the s23 ultra takes better pictures because it has a better zoom lens.
 
Reminder that the term “optical zoom” is incorrect as the iPhone does not actually zoom in.

It has a 5x prime lens that it switches to when necessary. All the “zoom” levels between the 3 prime lenses are just cropping of the sensor area from one of the cameras. This means that trying to take, for instance, a 3x photo on an iPhone 15 Pro Max will result in worse image quality than on an iPhone 15 Pro since it has to use smaller sensor area of main 1x camera to take the picture.

Yeah, this is a bugbear of mine. Not sure any of the 'zooms' from any manufacturer actually work as a proper zoom do they?
More correct surely to say they are telephoto lenses?
 
So it’s a reason that’s not really a reason. Because 10x would require steady hands or a tripod is not a reason to not offer it. People use tripods with phones. It’s a thing.
It absolutely is a reason to not offer it, because 99.999%+ of iPhone users are not hauling around a tripod. So if it's going to be onerous to use a 10X, that means almost no one is going to use it, and the results will, in many cases (not enough light) be poor. Meanwhile most people can handheld a 5X (stabilized) lens, and at f/2.8 it means it works well in all kinds of lighting conditions.

Unless you're suggesting they offer a 5X AND a 10X lens in the same phone, but it's not very practical.

One thing I could see them possibly doing in the future is adding a "doubler". This is an additional 2X magnifying lens that gets inserted via switch/level/electronic motor. It doubles the focal length of the base lens while also having the effect of halving the aperture. So this mechanism on the iPhone Pro Max could allow the user to switch between 5X f/2.8 and 10X f/5.6. (In traditional lenses, having the "doubler" active also typically makes the image a bit softer). So in a way, you could have the best of with worlds, with some compromises. However, these mechanisms might be too large or complex to make work in a phone format, and I don't know how they'd work with the prism design.
