【Zenfone 3 Big Update】

Camera optimization

After ZenFone 3 Deluxe, ZenFone 3 (ZE520KL / ZE552KL) also released a big OTA update 1703.28 (20170410) last month, I believe some of you are already using this verison, this version of the firmware did a lot of optimization for the camera, including:

1. Video autofocus

The previous version, we have to use some tips to enable the autofoucs, for this version is now set as defaulf. If you don't want autofoucs, you just need to press the screen once when you are shooting video, and the autofoucs will be turned off. Threre will be a icon on the upper left which says AF is off, you just need to press it again to enable it.


2. 快門釋放前預對焦。

In the previous version, when the shutter is pressed, the camera will decide whether to re-pre-focus the shutter before releasing the shutter according to the algorithm (eg composition change, subject distance change). The original intention was to ensure that the focus was successful when the photo was taken,in order to have the better quality, but some users may feel like taking a slow shot, the subject has run away.

The new firmware allows the user to decide whether to require pre-focusing. When you select "Smart Focus", you may re-focus when you press the shutter, and when you select Continuous AF, the exposure starts when the shutter is pressed, regardless of whether or not the focus is completed.

3. Optimize Zero Shutter (Zero Shoot).

Zero when the shutter refers to the camera is in a state of continuous capture of the image, press the shutter directly to retain the "screenshot", unlike the general camera APP is usually preview mode, take pictures instantly switch to camera mode.

Past conditions are at least 1/30 second, so when the camera is dark, the shutter is often only 1/25 or slower. When the shutter is pressed, the camera needs to switch mode, and there is no light. Smooth.

Now changed to shutter in about 1/20 (speculation), can start zero shutter, so that camera experience more smoothly.

4. Optimize 1/2 sec shutter delay.

The last 1/2 second shutter to complete the camera time is twice the 1 second shutter, unreasonable. After fixing a bug and optimizing the driver, it is now back to normal.

5. Adjust the balance between the slow shutter and ISO.

In the past automatic mode, when the lack of light will give priority to enhance the ISO, shutter speed as much as possible to maintain more than 1/30 seconds, the slowest to 1/8 seconds; now try to maintain the 1/20 seconds (keep zero shutter), the slowest It is reduced to 1/4 second.

6. other.

Optimize camera startup speed.

Optimize touch. Long press the shutter almost immediately after the continuous shooting.

Optimize camera speed within camera view.

In addition, the optimization on whether to open, you can refer to the following figure:

ISO 40000 can not see the obvious difference between the two, ISO 3200 can be seen when the open optimization will be noise reduction, close optimization is completely not dealt with (even before the closure of optimization is also suspected to have a secret part of the system ..)

But the scene to see the naked eye, dirty corrugated is the real appearance, although after the noise reduction but not true.

in conclusion:

No need to wait! Just Update it!!

remind:

1. Any upgrade is at risk, be sure to back up important information to the outside.

2. After the upgrade can not double, but it is recommended to restore the camera default value.
