The iPhone has a great built-in camera, but shooting with a flat iPhone can be awkward and even make for shaky photographs. However, if you want to minimize this shake, you can use the Snapgrip for iPhone 5 and 5S.
The Snapgrip is an iPhone case with a removable photography controller. This controller gives iPhone photographers tons of control over their iPhone’s camera. For instance, if you half-press the shutter, your iPhone’s camera will focus. The case also has a flash button, shooting mode wheel, and zoom controls for easy access to important functions when using the Snapgrip iOS app. Additionally, the bottom of the case has a standard tripod mount.
