The same 48-megapixel main camera, where is the Pro of the iPhone 15 Pro?

The Apple press conference, known as the Spring Festival Gala in the technology world, has gradually become like the real Spring Festival Gala. Consumers are more concerned about the shortcomings of this year than the hard work this year. Speaking of the shortcomings of the iPhone, in addition to Apple's lack of innovation, Cook's precise "knife skills" are also one of the key points of complaints from consumers.

At first glance, the iPhone 15 standard and Pro versions appear to have the same 48-megapixel main camera, but this is not the case. Even though the pixel density is the same, there are some subtle differences between the two.

The well-known foreign disassembly website iFixit discovered the differences between the iPhone 15 standard version and the Pro version in the latest disassembly video. iFixit said in the video that the iPhone 15’s sensor is about 22% smaller than the iPhone 15 Pro Max, so its performance in dark light scenes will be inferior to the Pro version.

The iPhone 15 Pro is equipped with a 1/1.28-inch sensor that supports four pixels in one, with a single pixel size of 1.22μm, while the iPhone 15 is equipped with a 1/1.56-inch sensor with a single pixel size of 1.0μm.

It is worth noting that the main camera of the iPhone 15 standard version is not the main camera of the iPhone 14 Pro series, but uses a new sensor. This kind of treatment is not even available to the iPhone 15 Pro series. It can be seen that Apple has put a lot of thought into distinguishing the shooting experience of the standard version and the Pro version.

Judging from the parameters, the iPhone 15 Pro not only has a larger sensor area, but the single-pixel size is also slightly larger than the standard version. In theory, a larger sensor would have an advantage over a smaller sensor because a larger area can collect more light, and the same goes for a larger single-pixel size.

Large pixels can increase the amount of light, reduce noise and ultimately improve image quality. However, large pixels also have disadvantages, the most important of which is that they reduce the resolution of the image. However, this shortcoming can be compensated by algorithms, so the impact is not significant.

In addition, there are some differences between the iPhone 15 standard version and the Pro version that were mentioned at the press conference. For example, the Pro version can shoot 7 different focal lengths through cropping and other methods, and supports 25x digital zoom (iPhone 15 Pro Max exclusive) and supports spatial video shooting, etc.

Even though the iPhone 15 Pro has advantages over the iPhone 15 in terms of functionality and imaging, it cannot be denied that the gap in photography capabilities between the two has been significantly reduced compared to the previous generation.

Taking the iPhone 14 series as an example, the iPhone 14 Pro Max has a 48-megapixel main camera and a 1/1.28-inch sensor, while the iPhone 14 maintains a 12-megapixel main camera and a 1/1.9-inch sensor. The sensor and pixel density can be said to be completely different.

Of course, the purpose of Apple's doing this is to distinguish between ordinary consumers and professional consumers, so Apple is trying to control the gap between the two so as not to make the iPhone standard version too inferior to the iPhone Pro version. So we can see an interesting phenomenon. ——Starting from the iPhone 14 series, the aperture of the standard version tends to be slightly higher than that of the Pro version.

The main camera apertures of iPhone 14 and iPhone 15 are f/1.5 and f/1.6 respectively, while the main camera apertures of iPhone 14 Pro and iPhone 15 Pro are both f/1.78. On the one hand, a large aperture can accommodate a higher amount of light, which to a certain extent makes up for the shortcomings of a small-sized sensor. On the other hand, a large aperture has better background blur capabilities, and users can easily take a picture suitable for "friends". "Circle" photo.

These subtle hardware differences between iPhone 15 and iPhone 15 Pro can be seen in Apple’s segmentation between high-end and low-end models, from one large and one small in the iPhone 6 era, to the number of lenses of iPhone 11, to the Pro and iPhone 15 Not Pro. Apple is no longer simply "cutting off", but analyzing the needs of different target audiences and accurately using surgical-level "knife skills" to make more detailed distinctions.
