What is laser focusing technology?

Laser focus technology is a technology commonly found on professional cameras. This technology uses a receiver and emits laser beams to detect the subject to be photographed, thereby helping the camera to focus quickly.

Laser focus not only helps the camera to focus faster, but also makes the selected image area clearer and more detailed. The current laser focusing speed is about 0.03 seconds, which is 3 to 4 times the normal focusing speed.

In addition, the combination of flash and laser beam will help your phone take pictures in low light conditions much better.

What is laser focus technology and how does it work?

First, your phone will fire an infrared laser beam at the subject you want to capture at the speed of light. The laser beam is emitted as light pulses and when it encounters an obstacle, it will be reflected back to the laser sensor, helping the camera to focus quickly.

The laser’s very fast speed makes distance measurement also near-instant and accurate regardless of environmental conditions such as temperature, humidity and light.

The laser focus feature helps the phone focus quickly and works well in low light conditions, but it still has some limitations when shooting landscapes or when the subject is too far away to make the laser beams. cannot be touched.
