Most consumer drones come with cameras built in. Most professional drones don't. The latter are built for pro-quality cameras, which is why Sony made the ILX-LR1. It packs a 61-megapixel full-frame back-illuminated Exmor R CMOS image sensor into a compact, lightweight body, thanks to the lack of a viewfinder, screen, or battery — all things you'd find on a "normal" camera. It has a single terminal capable of accepting power, as well as exposure output, focus, and trigger commands, and supports a wide array of E-mount lenses for an equally vast range of creative opportunities.
