Camera features

The Xiaomi offers more flexibility for portraits, landscapes, macro-style close-ups, and distant subjects. Its floating telephoto camera can focus from around 10 cm to infinity, allowing it to handle both close-up detail and telephoto photography.
→ Pro tip: If cameras are important, the Xiaomi is in a different class. The POCO focuses more on performance value than camera versatility.
