Yes. You can think about the lens like the mirror on the far side of car from the driver - "Objects in mirror are closer than they appear". Same physics principles, just using a curved piece of plastic instead of a curved mirror.
I'm not sure how you're not noticing lag. Just using my phone camera there's about 0.25 seconds delay between reality and what's shown on the screen, which is particularly noticeable if I swing my arm through the frame. And my phone's not trying to do any augmented reality, it has a static "HUD" that's constantly overlaid. With a Raspberry Pi receiving the camera signal and adding a moving overlay to the video before re-encoding and outputting it, I'd expect more delay.
You're effectively trying to build a smaller, faster version of what was used in this demo (which, to be fair, is trying to show a delay)
You'll have to say if the Field of View trade off is worth the lag.
