Huawei's P20 Pro started the trend towards the end of last year and now triple-cameras are quickly becoming the norm. Samsung just launched the Galaxy A7, a mid-range device that features a triple-camera on its rear.
A 24MP / F1.7 main camera is joined by an 8MP / F2.4 super-wide-angle with a 120-degree field of view and a third 5MP module is reserved for creating the background-blurring fake bokeh effect in portrait mode. So, unfortunately the Samsung's triple-cam setup does not come with a tele lens but maybe that's too much to ask from a mid-ranger at this point.
The rear camera uses Samsung's Intelligent Scene Optimizer system, which uses scene recognition to automatically adjust contrast, brightness and color for optimized image output.
