# Setting Camera Focus

The PRISM mobile app provide the ability to set the focus manually or automatically through the Camera Pro menu, which can be accessed by clicking the round More button in the upper left corner of the app screen.

But you can easily switch between Auto Focus and Manual Focus without entering the Camera Pro menu, by **Focus Mode** setting function in the More menu list.

The page below provides a simpler way to change focus without accessing the More menu.

## Default focus mode <a href="#b294" id="b294"></a>

If you do not touch the screen after launching the PRISM mobile app, the PRISM app is in Auto Focus mode. The camera automatically focuses on the preview image provided through the lens.

## Focus changes when screen tap <a href="#id-9ac7" id="id-9ac7"></a>

The way focus changes when you tap the screen depends on the current focus mode.

**case 1: Screen tap in Auto Focus mode**\
If you tap the app screen in Auto Focus mode, the app automatically focuses once and stays in Auto Focus mode. At this point, a white focus indicator with a picture of an open lock (meaning Auto Focus mode) is shown where you have touched it.

​

**case 2: Screen tap in Manual Focus mode**\
If you tap the app screen in Manual Focus mode, the app focuses once around the touched location and stays in Manual Focus mode. At this point, a yellow focus indicator with a picture of an closed lock (meaning Manual Focus mode) is shown you have touched it.

## Focus changes when long press

The way focus changes when you long press the screen also depends on the current focus mode.

**case 1: Long press in Auto Focus mode**\
If you long press the screen while in Auto Focus mode, the focus indicator turns white with an animation of the lock closing, and it switches to Manual Focus mode.

**case 2: Long press in Manual Focus mode**\
And if you long press the screen while in Manual Focus mode, the focus indicator turns yellow with an animation of the lock opening, and it switches to Auto Focus mode.
