At the second hardware conference this fall, apple spent a lot of time introducing the 12MP rear camera of the iPhone 12 series smartphone. We were deeply impressed by its powerful weak light shooting performance. But @ halidecamera tweeted that this was partly due to a 27% increase in aperture. In addition, through the data read from the app, we have a more comprehensive understanding of the camera parameters of the iPhone 12 Pro model. < p > < p > Matthew panzarino shared the parameters read on twitter. It can be seen that the new generation of iPhone has ushered in great improvements in the aperture and ISO parameters of wide-angle / ultra wide angle lens. < / P > < p > the software shows that the three rear cameras of the iPhone 12 Pro are all 12MP pixels, supporting the creation of 4032 × 3024 resolution images, supplemented by a larger aperture. < / P > < p > first, the wide-angle side. The aperture size of the corresponding lens of the previous generation iPhone 11 was f / 1.8, but the iPhone 12 has been upgraded to f / 1.6, which means that it allows more light to shine on the sensor. The second is the long focus lens and the ultra wide angle lens, whose apertures are f / 2.0 and F / 2.4, respectively. < / P > < p > the equivalent focal length of each camera of iPhone 12 Pro is still 13mm, 26mm and 51mm. The phase contrast autofocus system is also the same as the previous generation products (for example, ultra wide angle lens only supports PDAF relative detection autofocus). < / P > < p > the recognition data also shows the minimum and maximum exposure range (1 / 71000 to 1 second) for the wide-angle lens of the iPhone 12 pro, and 1 / 45000 to 1 second for the long focus and ultra wide angle ends. In addition, although the ultra wide angle end is still 5p lens, the wide-angle end has been upgraded to 7p lens.
