What is it? EM Camera and how it works

EM Camera (or Electromagnetic Camera) is a type of camera module that uses an electromagnetic actuator to focus, and unlike traditional stepper motor systems, a magnetic field is responsible for moving the lenses, which allows you to achieve a goal of focusing:

• ⚡ Higher focus speed – the reaction to changing the scene is almost instantaneous.
• 🎯 Accuracy even when shooting moving objects or in low light conditions.
• 🔋 Energy efficiency – electromagnetic drive consumes less energy than mechanical analogues.
• 🛠️ Durability – lack of mechanical parts reduces the risk of wear.

Technology EM Camera is not exclusive to Xiaomi — it is used by other manufacturers (for example, Oppo or Vivo), but in the devices of the brand it is often combined with proprietary image processing algorithms, such as: AI Scene Detection or Night Mode 2.0. EM Camera is not a separate sensor, but a type of autofocus that can be integrated into a main or telephoto module.

Compared to Laser. AF (laser-focus), EM Camera is better at macro and portrait photography, which requires smooth background blur (bokeh), but in total darkness, laser autofocus can be more accurate by directly measuring the distance to the object.

In which smartphones Xiaomi is EM Camera

Technology EM The Camera is not used in all Xiaomi models, but is found mainly in flagships and some mid-range devices. Below is a list of key smartphones with support for electromagnetic autofocus:

2. Use applications for diagnosis, for example, CPU-Z or AIDA64 (camera).
3. Check for the inscription. EM AF Manual shooting mode (Pro Mode in the standard camera app).

💡

If there is one on your smartphone EM Camera, try to turn off AI-Optimization in camera settings – this will help to evaluate the “clean” operation of autofocus without software improvements.

EM Camera vs. Other Types of Autofocus: Which is Better

The choice of autofocus technology depends on the use cases. EM Camera with other popular solutions:

• 🔍 Phase Detection AF (PDAF): Hurry up. EM Camera in good lighting, but loses exactly when shooting small details.
• 💡 Laser AF: It works best in complete darkness, but can be "lost" on transparent or reflective surfaces.
• 📱 Dual Pixel AF: Optimal for video due to smooth focusing, but more energy-consuming EM Camera.
• 🤖 Contrast AF: The slowest and most outdated option, found in budget models.

EM Camera in Xiaomi smartphones is most often combined with PDAF Laser AF To compensate for the weaknesses of each method, for example, in the Xiaomi 13 Pro, the main module uses the same method. EM AF For macro and portraits, and laser autofocus for general accuracy, which avoids "mistakes" when shooting in difficult conditions.

If you often take pictures:

• 🌃 At night → Laser priority AF or Dual Pixel.
• 👤 Portraits → EM Camera will give a more natural background blur.
• 🎥 Video → Dual Pixel or Hybrid Systems.

How to turn on and set up EM Camera for the best photos

Most of the Xiaomi smartphones with EM Camera doesn't have a separate switch for this technology -- it works automatically:

1. Activate Pro Mode: Manually (Camera Settings) → Pro) you can manually adjust your focus, which is useful for macro photography. AF-S (single autofocus for static objects or AF-C (continuous.
2. Turn off unnecessary filters: Functions like AI Beauty or Scene Detection can interfere with accurate focusing. → AI-camera.
3. Use the composition grid: Turn on the grid in the camera settings (the rule of thirds option) This will help to correctly position the object in the frame and simplify the operation of autofocus.

For portraits with a blurred background:

Open Portrait Mode in the Camera App

Make sure the distance to the object is 1-2 meters.

Click on the screen to manually select the focus point

If autofocus is not working properly, try:

• 🔄 Reboot your smartphone (sometimes helps with software failures).
• 🧹 Clean the lens of dust and fingerprints.
• 📱 Reset the camera settings to factory (Settings) → Annexes → Camera. → Warehouse → Drop it).

💡

EM Camera is particularly effective in close-range (macro) or portrait photography, and for landscapes and videos, it is better to rely on hybrid autofocus systems.

Common problems with EM Camera and how to solve them

Despite the benefits, EM Camera can run into problems, and here are the most common ones and how to fix them:

⚠️ Note: If the autofocus completely stopped working (lenses do not move, you can hear grinding), this may indicate mechanical damage. In this case, self-repair is not recommended - contact the Xiaomi service center.

If the problem persists after all the manipulations, check:

• 📲 Updates: Go to Settings → The phone. → Updating the system.
• 🔧 Camera Calibration: In the Engineering Menu (code ##4636##) find the Camera section and run the autofocus test.

In rare cases, malfunction EM Camera can be associated with damage to the camera plume, which is typical for phones that have fallen or been exposed to moisture:

• The camera is not focused at all (the image remains blurred).
• When switching between modules, an error occurs.
• The camera app appears a message Failed to connect to the camera.

EM Camera in the video: pros and cons

When you're filming a video EM Camera demonstrates both strengths and weaknesses, and on the one hand, the electromagnetic drive allows smooth and silent movement of the lenses, which is critical for dynamic scenes. On the other hand, some Xiaomi models may experience a “breath” of focus (permanent micro-tuning), especially when lighting changes.

Advantages EM Camera for video:

• 🎬 Quiet work - there is no characteristic buzzing of the stepper motor.
• ⚡ Rapid reaction to a scene change (e.g. when shooting sports events).
• 🔋 Energy efficiency – less heat and battery consumption compared to the Dual Pixel AF.

Disadvantages:

• 🌑 Problems in the dark - can "lose" focus when a sharp change in lighting.
• 📏 Limited range – Very close or long distance accuracy may be lacking.
