Have you ever noticed a strange app called Lens on your Xiaomi smartphone and wondered why you need it when you already have a standard camera? Many users mistakenly think it’s duplicate or unnecessary, but it’s actually a powerful tool with unique features that aren’t in the basic camera app. In this article, we’ll go into detail what the Lens app is, how it came to be in the Xiaomi ecosystem, and why it should be used even by professional photographers.
It's worth clarifying right away: The lens is not just an alternative launcher for the camera, but a separate product from Xiaomi designed to enhance the shooting experience. Unlike the standard Camera app, here you will find tools for working with macro photography, documents, QR-codes and even AR-effects that are hidden or unavailable in the main camera, and the application is closely integrated with Mi services. AI, This allows you to automatically improve your images without manual processing.
If you have ignored this icon on your desktop, after reading the article you will learn how to use it to take clear pictures of small objects without a professional macro lens, quickly scan documents with automatic perspective correction, and use hidden shooting modes, which are not told even in official instructions.
What is the “lens” application and why it is needed
The Lens app is a specialized tool from Xiaomi designed for advanced work with the smartphone camera. Unlike the standard Camera app, which is focused on universal photography, the Lens focuses on specific tasks:
The first version of the app appeared in 2019 along with the Mi CC9 line, but it was mass distributed only in 2021-2022 on devices with Snapdragon 8xx and Dimensity processors. Today it is pre-installed on most flagships and mid-budget models of Xiaomi, Redmi and POCO, but many users still do not know about its existence.
The main advantage of the Lens is that it automatically optimizes for a specific task, for example, when shooting a document, the application itself determines the boundaries of the sheet, removes shadows and distortions of perspective, and in macro mode it blocks the focus on a small object, preventing blurring. In a standard camera, you would have to manually adjust the exposure, white balance and focus.
Differences between the “lens” and the standard Xiaomi camera
Many people mistakenly think that the Lens is just a simplified version of the camera, but in fact it has a few key differences that make it indispensable in some scenarios.
| Function | Standard camera. | Annex “Lens” |
|---|---|---|
| Macro regime | Requires manual focus setting, often blurs edges | Automatic focusing up to 2 cm, stabilization |
| Scanning of documents | No or no third-party applications required | Automatic alignment, cropping, text improvement |
| QR/barcodes | It recognizes only in photo mode, often with a delay. | Instant scanning with link or information output |
| AR-effects | Limited set of stickers and masks | Extended. 3D-effects, integration with Mi AI |
| Photo processing | Basic filters and correction | Automatic improvement of contrast, sharpness and color |
Another important difference is speed, and the lens is optimized to run specific modes quickly, for example, if you need to scan. QR-code, the application will open the camera immediately in scan mode, whereas in a standard camera you will first have to select the appropriate mode in the menu.
However, the “lens” has limitations:
- ⚠️ No Pro mode (manual setting) ISO, exposure, white balance).
- ⚠️ No shooting in format. RAW.
- ⚠️ Not all effects are available on budget models (ARCore support required).
💡
The lens is ideal for fast tasks (scanning, macro, QR), and the standard camera is for creative shooting with manual settings.

Hidden Lens features that 90% of users don’t know about

- 📐 Measurement of objects In mode AR You can measure the length or height of objects (e.g. furniture — ±5% Only works on ARCore-enabled devices (Google has a list of compatible models).
- 🔍 Supermacro with an increase 50x In some models (for example, POCO F5 Pro) in macro mode, digital magnification to 50x. The quality will be worse than on optics, but for a quick inspection of small parts (for example, chips) is suitable.
Another little-known trick is that if you hold your finger on the screen in Macro mode, you will have a manual focus setting (a sun slider), which is useful when autofocus is not able to cope with complex textures (for example, shiny surfaces).
