Arsenal 2's speed depends on the shooting mode you're using. This is because some modes require Arsenal 2 to perform calculations after you press the shutter, while others simply send a signal to trigger the shutter.

When shooting in Handheld Mode, Arsenal 2 is continuously calculating ideal settings. This results in a near-zero time delay when you press the shutter. Handheld shooting has other limitations -- learn more in the Handheld Shooting Overview.

In Manual Mode, you are choosing camera settings in the Arsenal 2 app. When you press the shutter, the Arsenal 2 device only needs to receive the signal from your phone. This results in near-zero time delay, assuming your camera has already applied your desired settings (e.g. adjusted the lens focus).

When shooting in Smart Mode, Arsenal 2 needs to calculate the settings before taking the shot. This results in approximately a 1/10th to 1/5th of a second delay between when you trigger the shutter and when the photo is taken.

If you are using Arsenal 2's multipoint or whole scene focus capabilities (designed for the needs of landscape photographers), there will be a longer waiting period while the focal distances are measured and calculations are performed. This can take up to a minute depending on the number of focal points set, the lens, and the light/contrast available in your scene.
