Take a look in the official product page: https://www.raspberrypi.org/products/raspberry-pi-high-quality-camera/?resellerType=home
The camera have a CS-mount ring adapter and a C-mount, I remember the first time that I got the camera, and when playing with the 9 min and 16 min lenses I got frustrated because I don't remember that you have to use the ring adapter for the 16 min.
Check the official documentation to see how to mount the adapter ring for different lenses.

What we can do with this lenses ?
If you check the previous diagram, you will see that we have 2 lens for our Raspberry, 16 mm and 6 mm, if you try to category by the lens type both have to be places as a type 1, Fish Eye type but there are more factors that we have to consider.
As you can see, the 6 mm lens is a basic one for normal photograph pictures. The 16 mm is a very good one but more expensive but it's not a real Tele lense like a large one that have a focus near to 135 mm.
Even that, if you would like to learn about photography bot are very good for it, and if you try to adjust them dynamically using a python program you will have a loot of options to play with Aperture, ISO, exposure, etc... for example to take long expose pictures.
