Amazon.com: Raspberry Pi Camera Module V2-8 Megapixel,1080p (RPI-CAM-V2) : Electronics

The camera module works well, but I had to go searching for information on the proper orientation of the ribbon cable when connecting to a Raspberry Pi (3B+ in my case). What I was unaware of was that the connector on the Pi side had a lift-up latch which then needs to be pushed back down to lock the connector in place. Once I did that, the camera worked….

But it was out of focus. After still more searching, I discovered that the V2 camera is preset to “infinity” focus, but that the focus IS changeable. It turns out that the plastic funnel-shaped piece included with the camera is a tool for adjusting the focus, something mentioned nowhere I could find. You push it against the front of the lens and turn one way or another to adjust. Of course, you’ll have to test a view after each adjustment to see the effect.

Once I got that out of the way, it worked very well, though the depth of field is rather shallow.
