iPhone 15 is ready for close-up
main learning point
- Rumor has it that the iPhone 15 will feature a zoom periscope lens.
- The 90-degree periscope extends the zoom range and reduces the camera bump.
- The 10x zoom is much better than the current 3x lens on the iPhone 13 Pro.
The iPhone 15 could feature a new lens design that could revolutionize the camera.
Rumors suggest that the 2023 iPhone 15 will use a periscope lens that can increase the optical zoom range to 10x. This will allow for incredible close-ups of distant subjects, better background blur, and open up a wide range of possibilities for Apple’s computational photography skills and techniques.
While many Android flagships like Samsung’s Galaxy S21 Ultra have long included telephoto lenses, the official launch of the iPhone 15 series is scheduled for 2023. [Apple] enough time to adjust your periscope lens [for] Great photo quality,” technical narrator Victoria Mendoza told Lifewire via email.
A periscope lens is exactly what it sounds like. It’s a lens that uses a mirror (or prism) to reflect light at 90 degrees, solving the biggest challenge of phone camera optics: the length of the lens.
To provide a high magnification zoom or telephoto lens, the lens requires more glass (or plastic) elements. It takes space that smartphones don’t have. So far, the answer has been bigger and bigger camera bumps, but that can only go so far. The answer is to put the lens in the camera and flip it over so it lays flat instead of sticking out. A periscope simply redirects light towards this lens.
All that extra space means Apple can add a true 10x optical zoom to the camera, up from 3x now on the iPhone 13 Pro. The next time you snap a photo of that weird-looking bird in the tree outside your apartment window, you might end up with a photo of a bird instead of a spot surrounded by too many trees and sky.
to get close
The obvious use for a 10x telephoto lens is to zoom in on distant subjects. For a 35mm film camera or full frame digital camera, 10x zoom is equivalent to 24mm-240mm.
This isn’t new: the Huawei P40 Pro Plus 2020 has a 10x perimeter lens that reaches 240mm. But the raw magnification of the lens itself is only half the story. What can Apple do when it combines this 10x range with incredible computational photography?
“I think the telephoto is the only lens that Apple is really behind. In the end, I would like to have more range with the 3x, but the quality of the photo is not that great unless there is a lot of light, and even then it is sometimes not as good as I would like ,”He said. iPhone user AirunJae. On the MacRumors forum.
However, long zooms aren’t all positive. They have two major drawbacks (besides their physical size, periscopes can be used). One is that they added a handshake. Another is that they generally pass less light than wider lenses of the same size.
As for light, Apple’s night mode has achieved impressive results and can combine information from other, more sensitive cameras to create hybrid images.
A solution to jitter has also been demonstrated. Many modern cameras reduce shake by swapping lenses or sensors to counteract hand motion. Apple recently added sensor-shift vibration reduction to the iPhone, which is likely to be an option we’re seeing in the iPhone 15. The sensor is smaller and lighter than a glass lens, especially at 10x zoom. , so it would be much easier to move them fast enough
The advantage of the iPhone?
A telephoto lens with optical stabilization is already a very valuable tool, but how to combine it with some technical magic? One of Apple’s best tricks is Portrait Mode, which simulates the background blur of larger cameras. The telephoto lens naturally produces more background blur, which helps provide more accurate depth data to the portrait mode algorithm.
“I think the telephoto is the only lens Apple is really behind.”
More flexible lens options are one of the remaining advantages of cameras over phones. Are you going to lose your big camera to a new periscope lens? Not so fast.
In some areas, dedicated cameras still outperform any phone camera. One is that your telephoto lens can be bigger, so it can capture more light. Another is that you can switch lenses and get large widths or large lengths as needed. You also get natural background blur, which is still much better than analog. And the sensor is bigger, which means more detail and better light-gathering ability.
Finally, cameras with viewfinders, buttons, buttons, and dials are easier and more enjoyable to use.
Still, for most people, a true 10x optical zoom will make all the difference in your photos. I can’t wait to see what Apple will do with it.
An iPhone With a Periscope Lens Could Change Everything
The iPhone 15 is ready for its close-up
Rumors say the iPhone 15 will feature a zoomtastic periscope lens.

The iPhone 15 might pack in a radical new lens design, which could revolutionize its camera.
According to rumors, the 2023 iPhone 15 will use a periscope lens that could extend its optical zoom range to 10x. That would allow amazing close-up shots of far-away subjects, better background blur, and opens up a whole range of possibilities for Apple’s computational photography tricks and gimmicks.
“While many Android flagships, like Samsung’s Galaxy S21 Ultra, have already featured telephoto lenses for a long time, the iPhone 15 series is slated to go official in 2023, which will give [Apple] enough time to tweak its periscope lenses [for] amazing photo quality,” technology explainer Victoria Mendoza told Lifewire via email.
A periscope lens is just what it sounds like. It’s a lens that uses a mirror (or a prism) to reflect light 90-degrees, thus working around the biggest challenge for phone camera optics—lens length.
To offer high-magnification telephoto or zoom, a lens needs more glass (or plastic) elements. This needs space, which a smartphone doesn’t have. The answer, so far, has been ever-bigger camera humps, but that can only go so far. The answer is to lay the lens down inside the camera, flipping it to sit flat instead of sticking out. The periscope just flips the light into this lens.
All that extra space means that Apple could add a true 10x optical zoom to the camera, up from the 3x now available in the iPhone 13 Pro. The next time you snap a photograph of that weird-looking bird in the tree outside your apartment window, you might actually get a picture of the bird and not a dot surrounded by too much tree and sky.
The obvious use case for a 10x telephoto lens is for bringing far-off subjects closer. In terms of 35mm film cameras or full-frame digital cameras, a 10x zoom is the equivalent of 24mm-240mm.
This isn’t new—the 2020 Huawei P40 Pro Plus has a 10x pericope lens that reaches 240mm. But the raw magnification of the lens itself is only half the story. What could Apple do when it combines this 10x range with its incredible computational photography skills?
“I feel like the telephoto is the one lens on which Apple is really behind. I like finally having a little more reach with the 3x, but the quality of photos isn’t all that great unless there’s a lot of light, and even then sometimes it’s not as good as I think it should be,” iPhone user AirunJae says in the MacRumors forum.

Long zooms aren’t all positives, though. They have two significant disadvantages (apart from their physical size, which the periscope works around). One is they magnify your hand shakes. The other is they typically let in less light than a wider lens of the same size.
Light-wise, Apple already does impressive work with its night mode, and it could combine information from the other, more sensitive, cameras to create a hybrid image.
The path to fixing the shake is also proven. Many modern cameras use shake reduction, shifting either the lens or the sensor, to counteract your hand movements. Recently, Apple added sensor-shift shake-reduction to the iPhone, and this is probably the option we’ll see in the iPhone 15. Sensors are smaller and lighter than glass lenses, especially 10x zoom lenses, so moving them fast enough is a lot easier.
A long, optically-stabilized telephoto lens is already a very valuable tool, but how about combining it with some tech wizardry? One of Apple’s coolest gimmicks is Portrait Mode, which simulates the background blur from bigger cameras. A telephoto lens naturally brings more background blur, which could help feed more accurate depth data to the Portrait Mode algorithms.
“I feel like the telephoto is the one lens on which Apple is really behind.”
More flexible lens choice is one of the remaining advantages cameras have over phones. Would the new periscope lens let you ditch your big camera? Not so fast.
Purpose-built cameras still beat any phone camera in a few areas. One is that their telephoto lenses can be a lot bigger and therefore gather more light. Another is that you can swap lenses if you like and get really wide or really long. You also get natural background blur, which is still far superior to simulations. And their sensors are way bigger, which means more detail, and better light-gathering abilities.
And finally, a camera with a viewfinder, button, knobs, and dials is just easier and more pleasant to use.
Still, for most people, a true 10x optical zoom will make a huge difference to their photos. I can’t wait to see what Apple does with it.
