Apple Testing Major Camera Upgrades for iPhone 18 Pro Models, Could Feature Variable Aperture and Improved Telephoto Lens

Highlights

• Apple is testing a dynamic aperture system that adjusts light intake for better low‑light shots.
• A wider aperture telephoto camera is being explored to improve light capture, reduce noise, enable faster shutter speeds and deliver stronger background separation.
• Reports suggest possible features like a teleconverter for extended zoom and a 24‑megapixel front camera.

We have been repeatedly getting reports on iPhone 18 Pro models’ possible camera upgrades. Adding to all the speculations is a latest post from a well-known industry tipster on Weibo. It seems Apple is testing two significant rear camera enhancements for its upcoming iPhone 18 Pro lineup. Here are all the details.

iPhone 18 Pro – Possible Camera Upgrades

Weibo-based famous leaker Digital Chat Station claims that Apple is currently experimenting with a new main camera featuring a variable aperture. This technology allows the camera to dynamically control how much light enters the sensor.

In low-light conditions, the aperture can open wider to capture more light, while in brighter environments, it can narrow to avoid over-exposure. A variable aperture is also expected to give users more control over depth of field, affecting how sharply subjects appear against the background.

This information aligns with several earlier reports suggesting that both the iPhone 18 Pro and iPhone 18 Pro Max will receive a variable aperture main camera.

In addition to the main camera upgrade, the leaker has reiterated that Apple is also testing a new telephoto camera with a larger aperture for the iPhone 18 Pro models. The current iPhone 17 Pro lineup uses a telephoto lens with an ƒ/2.8 aperture.

While this camera was upgraded to a 48-megapixel sensor from a 12-megapixel sensor, the aperture size remained unchanged. A wider aperture on the telephoto lens would mainly improve light intake, reduce noise, enable faster shutter speeds, and deliver better background separation.

Previous Reports on iPhone 18 Pro Camera Upgrades

Apple supply chain analyst Ming-Chi Kuo was the first person to report that the main rear camera on the iPhone 18 Pro models would support variable aperture. Kuo shared the update way back in December 2024. Then, a later report from October 2025 further stated that Apple was moving ahead with plans to introduce this feature in next-generation iPhones and had already begun discussions with component suppliers.

So far, Apple has never used a variable aperture camera system on an iPhone. The main camera in the last few iPhone Pro models has relied on a fixed ƒ/1.78 aperture with the lens remaining fully open at all times.

In contrast, Samsung Electronics previously introduced variable aperture cameras on the Galaxy S9 and Galaxy S10 in 2018 and 2019. However, the feature was dropped in 2020 due to increased device thickness and higher costs.

iPhone 18 Pro – What Else We Know?

Beyond these changes, other reports suggest that the iPhone 18 Pro models could also feature a teleconverter to extend the effective focal length and enhance zoom capabilities.

Additionally, Apple is rumoured to be planning a 24-megapixel front-facing camera. The iPhone 18 Pro series is expected to debut in the fall, alongside Apple’s first foldable iPhone.
