Convert your iPhone into a real camera. (Available for Android phones too.)

I never saw or used the Pictar One Mark II so I'm providing info from the company. However, there is a more advanced version (Pictar Pro) coming in March. You can find out about it at the company website. Look for the Kickstarter link at the top of the page. (As of 11/2/18) Here's the info on the current model: Pictar One Mark II is a powerful smartphone camera-grip that connects easily to most iPhone and leading Android models (see list on their website) and gives users unprecedented control over the smartphone camera through a user-friendly app. Pictar One Mark II is controlled by no fewer than five external buttons and includes a patented, revolutionary interface which uses sound frequencies to activate the camera, which saves battery power compared to the standard Bluetooth connection. Pictar One Mark II was born to address mobile photographers of all levels – from social recorders to professionals – who wish to get more from their smartphone camera and miss that good-old feeling of firmly holding and easily controlling a traditional camera. $99 to $109 depending on what smartphone you have.
