A handheld device is communicatively coupled with a camera. The handheld device includes a mounting feature connecting the camera, or housing thereof, to the handheld device. Specifically, the mounting feature includes inner locking portions to engage with the camera, or housing. The handheld device further includes a handle housing to secure at least a rotating membrane and a communication subsystem. The rotating membrane includes multiple switches. The handheld device receives a selection of a switch from a user of the handheld device. The handheld device conducts a lookup in a lookup table for a setting mapped to the selected switch. The communication subsystem transmits a command to the camera, the command including the setting.
