Confusion About Raspberry Pi Camera Pinout – 15-Pin vs. 22-Pin

I’m currently learning about Raspberry Pi camera pinout and trying to connect a MIPI CSI camera module to my Raspberry Pi. However, I’m a bit confused about the 15-pin vs. 22-pin connectors.

Which Raspberry Pi models use the 15-pin CSI connector, and which ones require the 22-pin CSI connector?
If I have a 22-pin camera module, can I use an adapter to connect it to a Raspberry Pi with a 15-pin CSI interface?
Are there any specific compatibility issues I should be aware of when selecting the right connector?
I’d appreciate any insights or recommendations, especially from those who have successfully integrated different camera modules with Raspberry Pi. Thanks in advance!
