Apple’s new iPhone 18 Pro and 18 Pro Max come with a camera lens that Apple itself likely cannot repair. iFixit’s latest teardown shows the inner workings of the variable aperture mechanism, and the verdict is clear: it is a marvel of engineering, and it is nearly impossible to fix.
The lens uses six thin overlapping blades — each about as thin as a human hair — arranged in a magnetic system that opens and closes to control how much light hits the sensor. iFixit calls it “a feat of precision engineering,” and the photos taken through an Evident DSX2000 microscope back that up. The mechanism fits into the same main camera space as the iPhone 17 Pro series, and the scale comparison shows just how tight the fit is.
Impossibly thin blades
The blades themselves are each about as thin as a human hair. They overlap to form the mechanism that opens and closes magnetically, controlling how much light passes through to the sensor. The fit is so tight that the mechanism occupies the same space as the older iPhone 17 Pro series cameras.
A lens that cannot be fixed
If something breaks, the fix would require specialist tools, techniques, and knowledge that few people possess. iFixit says the mechanism itself probably cannot be fixed if it fails, and that means users will likely have to replace the entire camera assembly. Doing so would require techniques and knowledge that few people possess, according to iFixit.
That is a massive problem for anyone who wants their phone fixed. Replacing the whole assembly is not the same as a simple lens swap, and it is certainly not a job for the average repair shop.
Easy to access, hard to repair
The good news is that the camera assembly is thankfully easy to access. That means a professional repair shop can get to it without much trouble, but the cost will likely be steep.
Apple has not released components for its latest iPhone models yet. The iPhone 17 Pro camera assembly costs $249. Given that, we can probably expect the fancy variable aperture lens to increase the repair price for the 18 Pro and Pro Max versions.
The review’s verdict
iFixit’s review of the iPhone 18 Pro found that the adjustable aperture made a “generally marginal” improvement on overall photography. Novice snappers may not even notice any difference.
The review’s own line on the repairability is worth repeating:
“a feat of precision engineering.”
That is the same review that found the improvement marginal. The two statements sit side by side, and the contrast is telling.
Looking at the scale
The scale of the assembly is worth a second look. The blades are thin — each about as thin as a human hair — and they fit into a space that matches the iPhone 17 Pro series. That is a tight fit, and it is part of why the mechanism is so hard to repair.
A side-by-side image taken using the Evident DSX2000 microscope shows the comparison in full. The lens assembly is packed into a space that would not have room for it otherwise.
What the repair bill looks like
Apple has not released components for the 18 Pro series yet. The iPhone 17 Pro assembly costs $249, and the new variable aperture lens will likely increase that price further.
That is the economic reality of owning this camera. The lens is a precision marvel, but the price of repair is the number that will matter when a lens fails.
The choice Apple made
Apple has built a camera that is as close to impossible to repair as it gets, and that is a choice with consequences. The repair cost will likely be steep, and the phone will be harder to fix than the one it replaced.
The irony is that a camera this precise is also this fragile. The two are not natural partners, and the review makes that clear. The lens is a feat of engineering, and it is also a repair nightmare.
That is the whole story, and it is worth remembering the next time someone hands you an iPhone 18 Pro to fix.
Repair prices for comparison
| Model | Repair price (estimated) |
|---|---|
| iPhone 17 Pro assembly | $249 |
| iPhone 18 Pro variable aperture lens | Likely higher |
