I tried the K&F Concept lens adapter, but the big caveat is the sensor size difference, so effectively you get a huge zoom factor. Using the Kit lens from my Canon, I either need to put the camera module meters away from my face or meeting participants are only going to see my nose. :)

I have a 18-55(?) which is blatantly overkill but might be easier to tune in that regard. Biggest concern I have right now is aperture size, and I certainly don't expect things to be perfect on the first try :)

The crop factor of this camera is about 5.6, so 18 mm behaves like a 105 mm telephoto. For a portrait shot the camera needs to be about 3-4 meters away from you.
