The standard iPhone 15 models and the Pro models may seem to have the same main cameras at first glance, but that’s not entirely accurate. As many smartphone enthusiasts are aware, the iPhone 15 Pro boasts a larger sensor, with a 1/1.28-inch 48MP sensor featuring 1.22µm-sized pixels, while the iPhone 15 has a 1/1.56-inch sensor with 1.0µm pixels.

In terms of camera performance, a larger sensor theoretically has an advantage over a smaller sensor as it can capture more light due to its larger surface area. Similarly, larger pixels allow more light to pass through. This is particularly beneficial in low-light conditions.

For those who are curious about the actual size difference between the main cameras of the iPhone 15 and iPhone 15 Pro Max, iFixit’s repair experts have provided a closer look. In a video they shared, it becomes clear that despite both phones having 48MP main cameras, the size difference is significant. According to the video, the iPhone 15 has approximately 22 percent smaller quad-pixel buckets compared to the iPhone 15 Pro Max, meaning it may not perform as well in low-light situations.

It’s worth noting that the iPhone 15 Pro and Pro Max’s main cameras offer additional versatility. Users have the ability to switch between different focal lengths when capturing photos, including 24mm (1x optical zoom), 28mm (1.2x), and 35mm (1.5x).

While the iPhone 15 Pro’s larger sensor improves its potential to be the best camera phone of 2023, the iPhone 15’s primary sensor is also quite capable. For the average user, there are likely to be minimal differences in the results obtained from these devices.
