Like all modern smartphones, Oppo has emphasised on camera system the most. Its front camera is a 16MP lens with an f/2.4 aperture which can shoot exceptional images. We tried it to take some selfies in daylight and dark with portrait and panoramic effects and the results were marvellous. 

Coming to its rear camera, this is a quad-cam system which consists of 48MP+8MP+2MP+2MP lenses. The primary 48MP lens that comes with the Sony IMX 586 sensor. Its 8MP wide-angle lens supports a 119˚ field of view with an aperture of f/2.2. in addition, there are two 2MP monochrome lenses (one vintage portrait and the other black-and-white portrait). 

Overall, we found this camera setup admirable and exceptional for taking portraits and outdoor photography. The ultra-wide 48MP lens lets you capture images with balanced light regardless of external environments.

The hardware on this cheap 5G smartphone includes MtT873V chipset with 128GB storage and 8GB RAM. It runs on the Android 10 with the Oppo’s latest ColorOS 7.2 operating system. Additionally, the battery on this Android phone is 4000mAh which means it can survive a long busy day.

The quad-cam system can fulfil your photography needs, thanks to high precision lenses. Its 4000mAh battery is another component that you will relish during a busy day.
