Accessing and using the Focus Screen
The Focus screen can be accessed by tapping the square focus icon in the upper right corner of the app. From this screen, you can tap on the live view image to select one or more focus points. For precision focusing tap and hold on the preview to see the focus point magnified. *This feature is currently only available on iOS
Single Point Focus
The default focus mode is a single point focus. When you select a focus point, Arsenal focuses your camera’s lens to the exact distance of the subject in that part of the scene. You can select a single point of focus from the main screen of the app by tapping on the live view where you’d like to set the focus point, or through the focusing screen.
Select multiple points in your image. We recommend selecting two points. The near point and the far point. Arsenal will control your lens to measure the distance of each focus point. It will then calculate the optimal focal position for the maximum sharpness of those points and set the lens to that distance. The formula Arsenal uses is a modified version of the hyperfocal distance formula.
Whole Scene Focus
Arsenal will control your lens to measure the closest and farthest distances in your scene. It will then calculate the optimal focal position for the maximum sharpness of the entire scene and set the lens to that distance. This setting is intended for landscape and architectural photography.
