iPhone 11 3 Camera Design

Apple recently announced it's next phone release, the iPhone 11. Along with the base model, Apple is releasing a "pro" version of the phone. One of the features of this pro model is a strange 3 camera design. The article linked below explains the purpose and reasoning behind this design.
The three cameras all work separately, each having a different function.

One lens is the standard 12-megapixel iPhone camera, not much different from the cameras on previous iPhone models. The only remarkable aspect being that each pixel is used in autofocus, something many other cameras don't offer. It also has an f/1.8 aperture improving shooting in low-light conditions.

The other lens, which is a new feature, is a wide-angle lens. This offers a 13mm equivalent focal length which is about 120 degrees, nearly equal to human vision. They decided to stick with the 12 megapixels on this lens as well. It allows less light in, which is normal for a wide-angle lens.

The third lens, they claim is a telephoto lens, although the article says calling it telephoto is a stretch. It offers a 2x digital zoom which is equivalent to a 56mm focal length. It is being called the "portrait lens" because this zoom makes for high-quality portrait photos when paired with software that automatically blurs the background. It also will include other auto lighting effects.



It will also offer "deep fusion" which takes 9 photos at different exposure and shutter settings, automatically sort them and chooses the best combination. This is for the purpose of improving sharpness and helping to reduce noise in the image. It will also have "night mode" which will use a combination of different exposures and optical stabilization to improve images taken in the dark.

I believe this feature will make for higher quality photos without much effort from the photographer. The wide-angle lens may be exciting to those who are into landscape photography but don't want to buy a dedicated camera and a wide-angle lens. With all that said, I think this will lower the barrier to entry of people mildly interested in photography and possibly bring more people into the art. Whether that is a good or bad thing can be up to you.
