- iPhone 18 Pro dummy units suggest a thicker rear camera module than the previous generation.
- Expected upgrades like variable aperture and new sensors could be driving the design change.
- Overall dimensions remain mostly similar, with only slight increases in height and width.
Apple is widely expected to bring notable camera upgrades to its upcoming iPhone 18 Pro models. Early iPhone 18 Pro dummy units now suggest these improvements could come with visible design changes, particularly around the rear camera module.
iPhone 18 Pro dummy units hint at more prominent camera setup
Images shared by Vadim Yuryev from the Max Tech YouTube channel show dummy models of the iPhone 18 Pro and iPhone 18 Pro Max. These units, typically made by accessory manufacturers using supply chain information, often provide an early glimpse at a device’s physical design, though they are not always fully accurate.
According to Yuryev, the camera system on these dummy units appears noticeably thicker. He noted that the black glass covering the lenses protrudes more than before, and the overall camera plateau seems slightly bulkier compared to the iPhone 17 Pro Max.
Aside from the camera module, the overall dimensions appear largely unchanged. The iPhone 18 Pro Max dummy is said to be marginally taller and wider while maintaining nearly the same base thickness when the camera bump is excluded.
How reliable are these dummy units?
Yuryev has expressed confidence in the accuracy of these models, pointing out that similar dummy units he received ahead of the iPhone 17 lineup turned out to be quite precise. The source is believed to be Sonny Dickson, a well-known figure in Apple-related leaks, although this has not been independently confirmed.
That said, dummy units are based on early supply chain information. While they can offer useful insights, they do not confirm the final design Apple will release.
Camera upgrades could be driving the change
Several camera improvements are expected for the iPhone 18 Pro lineup, which could help explain the increased thickness, at least in theory.
The main camera is rumored to feature a variable aperture, allowing users to control how much light enters the sensor. This could help reduce overexposure and offer more flexibility in achieving different depth-of-field effects.
The telephoto lens may also adopt a wider aperture, improving performance in low-light conditions by letting in more light.
Additionally, at least one model could include a new three-layer stacked image sensor developed by Samsung. This advanced sensor design is expected to improve responsiveness, reduce noise, and enhance dynamic range.

A possible shift away from slim camera designs
What makes this development unique is that it contrasts with a broader industry trend toward flatter, less intrusive camera modules. Many smartphone manufacturers are aiming for near-flush designs to improve aesthetics and handling.
If these dummy units are accurate, Apple may be putting camera performance over maintaining a slimmer camera profile. However, no previous leaks have explicitly suggested a thicker camera bump, making this claim somewhat unexpected.
Updated measurements suggest noticeable differences
Following the initial reveal, Yuryev shared additional measurements:
- Total thickness (including camera plateau): 11.54mm on the iPhone 18 Pro Max, compared to 11.23mm on the iPhone 17 Pro Max
- Total thickness (including lens bump): 13.77mm vs. 12.92mm on the previous model
These figures point to a measurable increase in camera-related thickness, if accurate.
As with all early leaks, these details should be viewed with a pinch of salt. Apple has yet to confirm any design changes, and refinements are still possible before launch. Still, the current information suggests that improved camera capabilities could come with subtle, but visible, design trade-offs.
