The Samsung Galaxy S III was released in May 2012 – almost ten years ago. The S-series has evolved significantly over the past decade and in addition to design and performance, the camera is also one of the key factors that make a smartphone line successful.
The third generation Galaxy S launched with a single 8MP camera on the back and a 1.9MP selfie camera on the front. A decade ago, things like multi-camera setups and OIS were still fairly unknown.
In fact, it wasn’t until 2015 that OIS appeared on the Galaxy S6. Then, in 2018, the Galaxy S9 brought the first telephoto lens to the lineup, the Galaxy S10 5G the following year added an ultra-wide-angle camera.
Galaxy S10 5G also adds 3D ToF sensors on the front and back. This addition didn’t last long, however, and Samsung eventually reverted to a computational approach to measuring distances to objects. Another short-lived feature is the dual aperture. The Galaxy S9 and S10 can switch between f/2.0 for taking photos in bright conditions to f/1.5 for low-light environments.
Another short-term trend is the front-facing iris scanner. This sensor was used for biometric authentication, but was dropped in the S10 generation when Samsung switched to an in-display fingerprint sensor.
The following year, the first Galaxy S phone with a periscope lens appeared (not counting the Galaxy S4 zoom – it wasn’t a periscope-style lens and to be honest, it was more of a camera than a phone). ).
Galaxy S20 Ultra has a periscope lens with a focal length of 103mm, 4x optical zoom. This is more than double what previous telephoto lenses offer, but it creates a gap that is too wide for the main sensor to fill with digital zoom. So, with the Galaxy S21 Ultra onwards, Samsung used both the standard telephoto (now 3x) and periscope lenses.
Today, the camera is one of the most prominent features on Samsung’s flagship, so it is likely that we will see even more impressive technologies in the future.
