Our photo booth app can use either the internal tablet camera or can wirelessly tether to several Sony cameras.
We currently recommend:
Sony Alpha a5100 Mirrorless Digital Camera with 16-50mm Lens
Sony Alpha a6000 Mirrorless Digital Camera with 16-50mm Lens
We also support:
Sony Alpha a5000 Mirrorless Digital Camera
Sony Cyber-shot DSC-WX500 Digital Camera
Sony Cyber-shot DSC-HX80 Digital Camera
Sony DSC-QX10 Digital Camera Module for Smartphones
With testing, all Sony cameras supported by the Camera Remote API should be compatible.
