iPad cameras don't differ much, but there are fewer distinctions. Recent iPads all have 12MP front cameras that can also auto-track head movement during video chats (called Center Stage), but the Pro models also have Face ID-enabled TrueDepth cameras that use infrared to scan your face and are capable of some 3D-scanning tricks and AR extras. All the rear cameras are 12MP across models and can record 4K video, but the Pro adds ProRes video recording support. iPads are generally equipped with really good cameras for tablets, but they're not as good as iPhones.
