Different sensor sizes

According to foreign users according to the iPhone 7 Plus sample EXIF ​​information obtained lens focal length data, and then calculated through calculations, iPhone7 Plus equipped with two dual-camera sensor size is not the same. Among them, the wide-angle camera sensor size is 1/3 inch, the equivalent focal length is about 28mm, as for a single pixel size is 1.23μm, exactly the same as the previous iPhone 6s.

The iPhone 7 Plus telephoto camera's sensor size is calculated by 1/3.6 inch, equivalent focal length of about 57mm, but when the size of the pixel area is only 1.1μm. Therefore, in the case of a smaller sensor size, it means that no matter what the noise reduction or image quality is, the apple seems to have adopted a more aggressive noise reduction algorithm on the iPhone 7 Plus, so the possible problem is that When viewing a photo, there is a certain loss of sharpness in the image.

Or double-shot glue

It is worth mentioning that, for the iPhone 7 Plus has the optical zoom and optical image stabilization features, there are netizens in the Post Bar gives their own views, said the iPhone 7 Plus two cameras can not work at the same time, it should also be "pseudo Double camera" or jokingly called "glue double shot". According to netizens, the iphone7 plus did not achieve continuous optical zoom through dual camera synthesis as expected, but instead switched between 1X and 2X magnification by switching the camera.

In other words, when the iPhone 7 Plus is shooting normally, the two cameras do not work at the same time, and there is no essential difference with the LG G5. The difference is that the LG G5 uses a second camera to zoom out (wide-angle), while the iPhone 7Pus uses a second camera to zoom in (telephoto). However, because of this "pseudo dual camera" design, it should also be the reason for the iPhone 7 Plus can have optical image stabilization, at least the current dual cameras have not yet achieved the optical image stabilization precedent.

The end of the year will be upgraded

At the same time, the netizen also based on the iPhone 7 Plus to get started video, speculated that the machine's dual camera working mechanism will be 1x and 2x "optical zoom" by switching the lens to achieve; and 2x-10x zoom by telephoto lens digital zoom ; And 1x-2x zoom is achieved by the wide-angle lens digital zoom.

However, the iPhone 7 Plus does not require the two cameras to actually cooperate in the shooting process, and the above-mentioned conversion of several modes achieves a smooth and seamless connection, which largely reflects Apple's optimization level. And the netizen also said that the iPhone 7 Plus really needs two cameras to work closely together, and it is a test of the blurring of the background of the tune-up skills. Of course, all of the above arguments are users' speculations. The working principle of the iPhone 7 Plus dual camera in the end has what kind of features, I believe that after the detailed evaluation in the future, we should get a more accurate answer.
