The camera module V1 is a 5 Megapixels camera based on OV5647 and the camera module V2 is an 8 Megapixels camera based on Sony IMX219.
Meanwhile, we have the raspberry pi wide angle camera which is based on OV5647 and compatible with the Raspberry Pi camera module V1. The wide-angle camera has a 160-degree view angle, pretty much can see any angle in front of the lens.
There is also a raspberry pi infrared camera, which provides the raspberry Pi night vision ability.
