Camera Features of a Smart Phone

Aperture of a phone camera

If you look at smart phone advertisements, you notice that in high-end smart phone range, what are always featured are details of camera superiority that comes equipped in the phones. One of the things described is aperture of the phone camera. The aperture is represented by f number as in f/1.4, f/1.8, f/2.0, f/2.2 and higher number of aperture. In addition to the aperture, camera specifications such as mega pixel size, ISO, and other features are also mentioned in details.


For example, Asus Zenfone Selfie is advertised to have 13 mega pixels for front and back camera each having different aperture. The back camera has f/2.0 while the front f/2.2. Samsung J5 Pro has even smaller aperture number: the back camera comes with f/1.7 and the front f/1.9. Technically speaking, the smaller the f number is, the more light comes into the lens. With more light coming into the lens, the picture will be brighter and more focused, even at low light condition.

A lot of phone users are of the opinion that a better smart phone has bigger mega pixel camera. For example, Sony Xperia XA1 comes equipped with 23-mega pixel camera but the aperture is bigger than Samsung J5 Pro, which has only 13-mega pixel camera with f/1.7. Which is better Sony Xperia XA1 or Samsung J5 Pro in terms of picture quality?

Mega pixel relates to the size of a photo. The more mega pixel a camera has, the larger the size of a photo is. Larger mega pixel cameras do matter when you would like to view any photos on your PC or if you would like the photo printed.


What phone features to consider depends on buyers’ purpose of having a phone. Some people do not care about camera capabilities; they are more concerned with RAM or CPU of the phone they would like to buy. Some others look at the phone camera first. If the camera has bigger mega pixel, they will buy it.
